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.
Vega-Lite provides a higher-level grammar for visual analysis, akin to ggplot or Tableau, that generates complete Vega specifications.
Try using Vega-Lite in the online Vega Editor.
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.
