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.
Use npm or yarn to install Vega for use in third-party libraries or applications.
Using npm:
npm install vega
or using yarn:
yarn add vega
If you would like to install the Vega command line utilities (vg2pdf
, vg2png
, vg2svg
), see the vega-cli
package.
