A visualization grammar.

Last update: Dec 30, 2022

Overview

Vega: A Visualization Grammar

Vega is a visualization grammar, a declarative format for creating, saving, and sharing interactive visualization designs. With Vega you can describe data visualizations in a JSON format, and generate interactive views using either HTML5 Canvas or SVG.

For documentation, tutorials, and examples, see the Vega website. For a description of changes between Vega 2 and later versions, please refer to the Vega Porting Guide.

Build Instructions

For a basic setup allowing you to build Vega and run examples:

Clone https://github.com/vega/vega.
Run yarn to install dependencies for all packages. If you don't have yarn installed, see https://yarnpkg.com/en/docs/install. We use Yarn workspaces to manage multiple packages within this monorepo.
Once installation is complete, run yarn test to run test cases, or run yarn build to build output files for all packages.
After running either yarn test or yarn build, run yarn serve to launch a local web server — your default browser will open and you can browse to the "test" folder to view test specifications.

This repository includes the Vega website and documentation in the docs folder. To launch the website locally, first run bundle install in the docs folder to install the necessary Jekyll libraries. Afterwards, use yarn docs to build the documentation and launch a local webserver. After launching, you can open http://127.0.0.1:4000/vega/ to see the website.

ES5 Support

For backwards compatibility, Vega includes a babel-ified ES5-compatible version of the code in packages/vega/build-es5 directory. Older browser would also require several polyfill libraries:

<script src="https://cdnjs.cloudflare.com/ajax/libs/babel-polyfill/7.4.4/polyfill.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/[email protected]/runtime.min.js"></script>
<script src="https://cdn.jsdelivr.net/npm/[email protected]/dist/fetch.umd.min.js"></script>

Contributions, Development, and Support

Interested in contributing to Vega? Please see our contribution and development guidelines, subject to our code of conduct.

Looking for support, or interested in sharing examples and tips? Post to the Vega discussion forum or join the Vega slack organization! We also have examples available as Observable notebooks.

If you're curious about system performance, see some in-browser benchmarks. Read about future plans in our roadmap.

width/height do not fully determine final graph size

When backend generates a graph, it needs to know the final size of the image in order to eliminate FOUC. This is especially important if the graph image is server-side generated - the HTML would need to contain the width/height of the image, so that the browser can lay out the page even before the image gets downloaded. The problem is that if the graph is user contributed, there is no way for the server to know the right size. We have been using top level width/height elements, but they are not the final results - vega can unexpectedly resize based on the presence of legend, marks whose coordinates are outside of 0..width x 0..height, large number of ordinal items in a scale, etc.

I think that before Vega3 is out, we really should clean up this aspect. Without this, we cannot reliably generate HTML, nor can we effectively support mobile devices, as they are tightly coupled with the screen sizes.

Add Arrow/Feather reader

There's been some discussion over in the Feather repo about using the Arrow JS implementation to add an Apache Arrow IPC interface to Vega/Vega-lite.

Adding this to Vega would save serialization costs when bringing data in from other contexts (like Altair does), allowing users to leverage Vega's aggregation and visualization capabilities while reading from arrow data with zero copies.

I'd love to support this endeavor - I'm familiar with Apache Arrow JS so I can absolutely support from that side, but I don't know much about the Vega codebase so I would need assistance there.

Add "flatten" transformation

A very common usecase we see with Elasticsearch results is visualizing multi-level aggregation results such as these, or in a simplified form:

[
  { key:'a', nested: [ {v:1}, {v:2} ]}
  { key:'b', nested: [ {v:3}, {v:4}, {v:5} ]}
]

which needs to be flattened out into a form usable by Vega:

[ {key:'a', v:1}, {key:'a', v:2}, {key:'b', v:3}, {key:'b', v:4}, {key:'b', v:5} ]

I would like to propose a flatten transform with these params. I think some of them are similar to the lookup transform.

{
  type: "flatten",

  // Should work the same way as "format.property" in "data",
  // e.g. allow values like "subfield[0].subsubfield".
  property: "nested"

  // Optionally keep just these fields from the current object (performance)
  // otherwise will keep everything.
  // For the above example, we don't need to keep the "nested" field in the result
  parentFieldsToKeep: ["key"]

  // Optionally copy just the selected values (performance)
  // otherwise will copy everything. Similar to "values" in lookup transform.
  // The above example has only the "v" field anyway, so this line has no effect.
  values: ["v"]

  // Optional, similar to "as" in lookup transform.
  // If subfieldToCopy is given, must be an array of the same size, otherwise must be a string.
  // For array, specifies that "v" (from above) should be set as "newV" in the object.
  // When copying the whole object, this is the 
  as: ["newV"]
}

Needs better param names.

Flattening object subvalues

This portion could be implemented at a later date. I did see a case like this, but I think this is less frequent than the above. Transform params are TBD.

[
  { key:'a',  nested: {foo:1, bar:2}}
  { key:'b',  nested: {foo:3, bar:4, baz:5}}
]

Expected result could be one of these. Either treat object as an array of one element:

[ {key:'a', foo:1, bar:2}, {key:'b', foo:3, bar:4, baz:5} ]

or convert each key-value pair into a separate object:

[
 {key:'a', k:'foo', v:1}, {key:'a', k:'bar', v:2},
 {key:'b', k:'foo', v:3}, {key:'b', k:'bar', v:4}, {key:'b', k:'baz', v:5}
]

The second case can be enabled with a flattenObjects: ["k", "v"], specifying the key-value field names. If the value is false, autoconvert objects to single value arrays. The default is TBD.

Flattening other values

In case the value is neither an array nor an object, we could treat it similar to the second variant of the object expansion. It becomes equivalent to a formula transform.

[ { key:'a', nested: "meaning" },  { key:'b', nested: 42 } ]

[ {key:'a', v:'meaning'}, {key:'b', v:42} ]

Multi-level and multi-item flattening

This could be solved by chaining several flatten transforms together. @jheer, if there is a significant performance hit of using several chained transforms to achieve this, lets define how to parametrize this. Otherwise, not worth it.

There are two cases when multiple flattening operations may be required: multiple lists in the same object under different fields:

[
  { key:'a',  nested1: [ {v:1}, {v:2} ],  nested2: [ {v:3}, {v:4} ]}
  { key:'b',  nested1: [ {v:5}, {v:6} ],  nested2: [ {v:7}, {v:8} ]}
]

The second case is sub-level with sub-sub-level

[
  { key:'a',  nested: [ { sub: [ {v:1}, {v:2} ] }, { sub: [ {v:3}, {v:4} ]}]}
  { key:'b',  nested: [ { sub: [ {v:5}, {v:6} ] }, { sub: [ {v:7}, {v:8} ]}]}
]

This array of 8 values is the expected result in both cases:

[
 {key:'a', v:1}, {key:'a', v:2}, {key:'a', v:3}, {key:'a', v:4},
 {key:'b', v:5}, {key:'b', v:6}, {key:'b', v:7}, {key:'b', v:8}
]

Problem with npm build of vega
I am using vega in another npm package and am having some build problems with it. When I try to build everything, I find that vega isn't able to resolve some packages that are declared as dev dependencies but not runtime dependencies. More specifically I had to add the following to my package.json:

"dependencies": { "browserify-shim": "^3.8.10", "browserify-versionify": "^1.0.6", "jstransform": "^11.0.3", "through": "^2.3.8", "vega": "^2.2.4", "vega-lite": "^0.7.15", }, "browserify-shim": { "d3": "global:d3", "d3.layout.cloud": "global:d3.layout.cloud", "canvas": "global:canvas", "topojson": "global:topojson" },

To get it to work. Are these meant to be actual dependencies or is something else off?

Tooltip hover not working properly on Windows PC - Vega 4.2.0
Hello,

My team and I are using Vega 4.2.0 (We would prefer not to upgrade to the latest version as it may break other parts of our app) and are encountering odd behavior with the tooltip only on Windows PC. For the bar charts, the tooltip does not correlate with where the user hovers the cursor. And for the line charts, the hover does not appear at all over the points.

Screenshots:

We have tested on different Windows and Mac computers and in the following browsers with these specs:

Chrome Version 76.0.3809.100

Firefox Version 68.0.1

Microsoft Edge 44.18362.1.0

The results seem consistent in that only Windows PCs experience this issue and it occurs in all browsers.

We have a test build, which you can use to reproduce the issue with here: http://alpha.blueraster.io/gfw-mapbuilder/new-report-consolidated-builds/default/

To replicate:

Click on the pencil icon in the right panel.

Click on the Start Drawing orange button.

Draw a shape anywhere there's land on the map (shape must have a minimum of 3 points (triangle) to close. Double-click to close.)

Select an analysis from the dropdown in the left panel.

Click on Print Report button.

The report view will generate Vega Charts for each analysis (some might fail or take some time to generate).

Hover over the bars in CO2 EMISSIONS FROM BIOMASS LOSS or the points in GLAD ALERTS PER MONTH (other bar charts appear slightly off as well).

For our Vega specs, here is the API call for the CO2 EMISSIONS FROM BIOMASS LOSS bar chart as an example: https://api.resourcewatch.org/v1/widget/ac38fdbd-fdb1-4d8e-9109-674013fb51a2?period=2001-01-01,2018-12-31&thresh=30&geostore=277e65fb0fbf5c6fb8f73143e559fc38& All of the specs for our charts are set up in a similar manner. We also add in {"type": "fit", "resize": true} and a signal to override the width:

{ name: "width", update: "containerSize()[0]*0.95", value: "", on: [ { events: { source: "window", type: "resize" }, update: "containerSize()[0]*0.95" } ] }

My team and I appreciate any assistance or suggestions on how to fix this bug. Thanks!

Logo and Branding for Vega and Vega-Lite

Vega still lives without a logo but it would be nice to have some recognizable branding.

We could go with the logo style that Altair uses: https://github.com/altair-viz/altair/issues/212#issuecomment-338428670

Let's use this thread for further proposals and discussions.

Optional `metadata` field

An optional metadata field at the top level of Vega and Vega-Lite specs can be used to add additional information to a spec that is ignored by the compiler. this metadata could be used by some custom preprocessing step.

@kanitw @jheer @arvind, please reply with 👍 or 👎 so that @ericsoco can move forward.

Responsive charts based on container size
This is a Vega 3 feature request: Provide a way to resize the graph based on the container's height/width.

With a combination of the window resize event and windowSize expression, there's a way to resize the graph based on the window's dimensions but not the container.

I've been told a workaround is to update the view instance with the containers height/width on window resize.

Example:

$(window).on('resize', function() { // assume I have an element and viewInstance variables representing // the container, and vega View instance, respectively. const $element = $(element) const width = $element.width(); const height = $element.height(); viewInstance.width(width).height(height).run(); });

Perhaps there is an easier and more elegant way to do this within Vega?

Vega-Interpreter/Angular 9: CSP unsafe-eval still needs to be activated

Hallo,

I am trying to use Vega-Interpreter in Angular 9 together with vega embed. In my CSP I do not allow unsafe-eval.

I have all my Vega logic in one service. Here is the relevant code snippet:

[..]

import * as vegainterpret from 'vega-interpreter';
import embed, {Mode,VisualizationSpec} from 'vega-embed';
import { Renderers } from 'vega';
 [..]

    embedOpts.config={};
            embedOpts.config.ast=true;
       await embed(element, spec, embedOpts);

Chrome throws the following error related to the CSP:

ncaught EvalError: Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of script in the following Content Security Policy directive: "script-src 'self' 'unsafe-inline'".
    at Function (<anonymous>)
    at field.js:10
    at Module../node_modules/vega-tooltip/node_modules/vega-util/src/accessors.js (accessors.js:6)
    at __webpack_require__ (bootstrap:79)
    at Module../node_modules/vega-tooltip/node_modules/vega-util/index.js (index.js:1)
    at __webpack_require__ (bootstrap:79)
    at Module../node_modules/vega-tooltip/build/src/formatValue.js (formatValue.js:1)
    at __webpack_require__ (bootstrap:79)
    at Module../node_modules/vega-tooltip/build/src/Handler.js (Handler.js:1)
    at __webpack_require__ (bootstrap:79)

I am not sure if further parts of Vega are affected as Chrome probably shows only the first issue and not the subsequent ones.

This means I cannot activate CSP for the whole application.

Did I apply the vega-interpreter wrongly? If not, how should I apply it? If yes, does the vega-interpreter only apply with embed, but not during general loading of the Vega modules?

Thank you a lot.

Incorrect types for Legend typings

The Legend typings size, shape, strokeDash, strokeWidth, and opacity are all string, which seems incorrect. I believe this is what leads to the vega-lite schema for Legend not showing strokeWidth, even though it is present in LegendConfig: https://github.com/vega/vega-lite/blob/f72d8be7fba154437ceaf51ec332d066c1e89313/build/vega-lite-schema.json#L7311

}

If you change the strength of the x and y forces in the above spec to 0.1, the following happens (observe position of axes gets shifted down and right creating white space at the top and left). The more particles in combination with very high or very low but equal x and y strengths make the problem even more apparent. I have a chart where I currently have to create a negative left and right padding to fit on the canvas.

view.finalize() throws an error when an event stream is configured to monitor a DOM element
Summary

When an event stream selector uses a CSS selector to monitor a DOM element, view.finalize() throws an error by attempting to call removeEventListener() on a NodeList. I am encountering this issue on Vega version 5.22.1.

Reproduction steps

A minimal reproduction is available here: https://codepen.io/ravron/pen/wvxoWep

Alternatively:

Create a signal attached to a button id with a CSS selector (see example spec below)

Create a view, like:
view = new vega.View(vega.parse(spec)) .renderer("svg") .initialize("#chart") .run();

Call view.finalize()

Expected behavior

No errors appear in the console, and all event listeners are removed.

Actual behavior

The following error is observed in the console:

Uncaught TypeError: n.sources[e].removeEventListener is not a function at HT.finalize (vega-view.module.js:385:20) at pen.js?key=pen.js-e7acd024-1796-2f60-e004-8dc0d83e7a07:21:6

and the event listener is not removed from the button.

Example spec

{ schema: "https://vega.github.io/schema/vega/v3.json", width: 500, height: 200, signals: [ { name: "button", value: false, on: [ { events: "#button:clicked", update: "true" } ] } ] }

Suspect code

The source of the problem is as follows. When tracking event listeners, function trackEventListener calls the array utility function on sources. When the source is a DOM element, sources is a NodeList. Unfortunately, the array function simply checks if something is a literal array, and if not, wraps it in one. Because a isArray(NodeList) === false, trackEventListener ends up recording an array with one element, a NodeList.

Later, finalize calls removeEventListener on each element of the sources array. Because in this case the sources array contains just one NodeList, finalize calls removeEventListener on a NodeList, which is undefined and causes the error observed.

I suggest wrapping document.querySelectorAll() in Array.from() here. This would convert the NodeList to an actual array, and it would prevent array() from wrapping it in another array.

v5.13.0(Jun 2, 2020)
Notable Changes

Improved Streaming Performance.

For performance, Vega caches a lot of internal data structures, including calculated tuples, scenegraph items, and SVG DOM nodes. Previously, nested scopes (such as those created for facetted data) that result in vega-runtime subcontexts were never cleaned. If no external View API calls are made, this is fine, and actually improves performance for interaction-driven dynamic filtering. However, when providing streaming data to Vega through the View API, uncleaned caches and subcontexts can result in substantial memory leaks that also eventually degrade performance.

This version adds mechanisms for clearing caches and detaching subflows to support streaming data within nested specifications. When input data is removed via a View API call or via signal-valued URL, Vega will now by default trigger garbage collection to reclaim resources. This behavior can be disabled by calling clean(false) on a constructed ChangeSet passed to the View API.

Improved Cursor Performance.

Previously Vega updated the cursor style on the HTML document body. This persists cursor settings even during interactions (such as drags) that may leave the Vega View component. However, it also can result in large performance penalties in Chrome, which re-evaluates CSS styles in response. This version changes the default behavior to set the cursor locally on the Vega View component. If a global cursor is desired, the boolean config property events.globalCursor can be set true or the View method globalCursor can be invoked to change the setting at runtime.

Optional Expression Interpreter.

This release adds interpreter support for Vega expressions that is Content Security Policy (CSP) compliant. By default, the Vega parser performs code generation for parsed Vega expressions, and the Vega runtime uses the Function constructor to create JavaScript functions from the generated code. Although the Vega parser includes its own security checks, the runtime generation of functions from source code nevertheless violates security policies designed to prevent cross-site scripting.

This release provides an interpreter plug-in (the new vega-interpreter package) that evaluates expressions by traversing an Abstract Syntax Tree (AST) for an expression and performing each operation in turn. Use of the interpreter enables compliance with CSP, but can incur a performance penalty. In tests of initial parse and dataflow evaluation times, the interpreter is on average ~10% slower. Interactive updates may incur higher penalties, as they are often more expression-heavy and amortize the one-time cost of Function constructor parsing.

Changelog

v5.12.3(May 23, 2020)
Notable Changes

The previous Vega v5.12.0 release introduced changes to how SVG was generated, including the addition of an internal stylesheet. However, this leads to integration issues with downstream tools (including at least one popular SVG optimizer) that do not support stylesheet parsing. In addition, local performance tests indicate faster rendering in Chrome when using presentation attributes instead of CSS styling. This version (v5.12.3) now changes the SVG output to favor presentation attributes (fill="blue") over CSS style (style="fill: blue;").

CSS styles have been removed in all but one case: the use of image-rendering for non-smoothed images, where browser differences require multiple style definitions to appease both Chrome and Firefox, something we can't express with presentation attributes alone. If and when Firefox properly supports image-rendering: pixelated we can consider dropping this last use of CSS.

Note that external stylesheets can still be used to style Vega SVG content, and may now have higher specificity due to the use of attributes.

v5.12.0(May 15, 2020)
Notable Additions

View-specific locale management for number and date formatting. The View constructor accepts a locale option, and Vega specs support a config.locale property. Locale objects should have number and/or time properties that map to valid d3-format or d3-time-format locale definitions.

View toCanvas now accepts an externalContext option to draw into a separately managed canvas instance. For example, one could draw multiple Vega views into the same node-canvas instance for server-side PDF document generation.

Initial support for signal-valued axis orient properties. This addition allows the position of an axis (e.g., left versus right) to be dynamically updated at runtime. The feature should be considered experimental; subtle bugs may still arise.

Internal refactoring to support content security policy (CSP) in the future. The Vega parser accepts an ast option flag to include generated abstract syntax trees for expressions in the parser output. All Function constructor use for generated code is now consolidated into a single file in the vega-runtime package and could be overridden if an expression AST interpreter is implemented.

Bug fixes! See below...

Preliminary support for ARIA accessibility attributes in SVG output.

Fix overflow with large domain and small tickMinStep (#2550, thanks @rwoollen!)

vega-scenegraph

Add ARIA attribute generation to SVG renderers:

Parent <g> tags for mark items include automatic role and aria-roleDescription attributes.

Parent <g> tags for axes and legends include automatic aria-label captions.

Attribute generation for mark and guide definitions can be customized using the aria and description properties. If aria is false, the content is hidden from the accessibility tree by setting aria-hidden SVG attribute. The description property determines the aria-label SVG attribute.

Individual mark items do not include ARIA attributes by default, but these can be added using the encoding channels aria and description. If a description is provided and aria !== false, then Vega will generate accompanying role and aria-roledescription attributes for a mark item.

Provide experimental ariaRole and ariaRoleDescription encoding channels for individual marks, which override the default role and aria-roledescription attributes generated by Vega. However, note that these are experimental features and so may change at a later date.

vega-schema

Add ARIA accessibility properties to mark, guide, and encode schemas.

Add axis domainCap, gridCap, and tickCap properties.

vega-time

Add dayofyear time unit support and corresponding tests.

v5.10.0(Mar 6, 2020)
Notable Additions

The Vega parser now generates a built-in background signal which the view uses to set the background color. While not technically a breaking change (specs will still parse and evaluate successfully), existing specs that use a signal named "background" may not render the same as before, in which case a different signal name should be used.

Top-level properties (autosize, background, padding, width, height) accept signal references, such as {"signal": "<expr>"}, which map to a signal definition's update property. If the top-level signals array contains an entry that matches one of these properties, the definitions will be merged, with precedence given to the properties defined in the signals array.

Vega views now include ARIA attributes on the view container DOM element. The role attribute is set to "figure", and the aria-label attribute is set to the specification description property.

The aggregate and window transforms support the product operation to multiply values.

The config supports a top-level lineBreak option for setting a global default for text line breaks. This property should be a string or regexp value, or a corresponding signal reference.

Support for text baseline values line-top and line-bottom. These values are similar to top and bottom baselines, but calculated relative to the lineHeight rather than fontSize alone.

Support for color blend modes via the new blend encoding channel. The allowed values are: multiply, screen, overlay, darken, lighten, color-dodge, color-burn, hard-light, soft-light, difference, exclusion, hue, saturation, color, luminosity. For Canvas rendering, the blend is set via the context 2D globalCompositeOperation property. For SVG rendering, the blend is set via the CSS mix-blend-mode style. The default Vega value is null (or undefined), which maps to the default values "source-over" (for Canvas) and "normal" (for SVG). For more, see the Canvas globalCompositeOperation and CSS mix-blend-mode documentation, including limitations in cross-browser support.

Support for configuration of cross-origin image handling. Vega uses crossOrigin="anonymous" by default for loaded images, which allows images loaded from a different host to be included in exported visualization images (and thereby avoid "tainted canvas errors"), so long as the server provides permission via proper CORS headers. This default can be overridden by providing loader options to the Vega view that include a crossOrigin property. If this property is defined and maps to a value of null or undefined, then a no-cors fetch will be performed instead.

Add axis labelOffset property to adjust axis label position in addition to tickOffset, and labelLineHeight to set the line height for multi-line axis labels.
