Vega: A Visualization Grammar

Vega Examples

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.
