Vegais avisualization 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 theVega website.For a description of changes between Vega 2 and later versions, please refer to theVega Porting Guide.
For a basic setup allowing you to build Vega and run examples:
- Clone
https://github /vega/vega. - Run
yarnto install dependencies for all packages. If you don't have yarn installed, seehttps://yarnpkg /en/docs/install.We useYarn workspacesto manage multiple packages within thismonorepo. - Once installation is complete, run
yarn testto run test cases, or runyarn buildto build output files for all packages. - After running either
yarn testoryarn build,runyarn serveto 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 thedocsfolder. To launch the website locally, first runbundle installin thedocsfolder to install the necessary Jekyll libraries. Afterwards, useyarn docsto build the documentation and launch a local webserver. After launching, you can openhttp://127.0.0.1:4000/vega/to see the website.
For backwards compatibility, Vega includes ababel-ifiedIE-compatible version of the code in thepackages/vega/build-es5directory. Older browser would also require several polyfill libraries:
