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.

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, run bundle install and bundle exec jekyll serve in the docs folder. The last command launches a local webserver. After launching, you can open http://127.0.0.1:4000/vega/ to see the website.
