The master branch hosts Vega-Lite 2.0. In Version 2, we have migrated Vega-Lite to use the new Vega 3, and include composition and interaction features from our research publication.
You can find Vega-Lite version 1 in our 1.x maintenance branch (website for Vega-Lite 1).
Vega-Lite provides a higher-level grammar for visual analysis, akin to ggplot or Tableau, that generates complete Vega specifications.
You can find more details, documentation, examples, usage instructions, and tutorials on the Vega-Lite website.
Try using Vega-Lite in the online Vega Editor.
Contributions are also welcome. Please see CONTRIBUTING.md for contribution and development guidelines and our Code of Conduct.
The development of Vega-Lite is led by Kanit "Ham" Wongsuphasawat, Dominik Moritz, Arvind Satyanarayan, and Jeffrey Heer of the University Washington Interactive Data Lab. Please see the contributors page for the full list of contributors.
