Vega

The Vega projects provide an ecosystem of tools for declarative data visualizations. The various components of this ecosystem build on each other providing different levels of abstraction.

Vega is a visualization grammar, a declarative language for creating, saving, and sharing interactive visualization designs. With Vega, you can describe the visual appearance and interactive behavior of a visualization in a JSON format, and generate web-based views using HTML5 Canvas or SVG.

Vega-Lite is a high-level visualization grammar. It provides a concise JSON syntax for supporting rapid generation of visualizations to support analysis. Vega-Lite support interactive multi-view graphics. Specifications can be compiled to Vega.

Vega-Altair is a declarative visualization library for Python. Its simple, friendly and consistent API, built on top of the powerful Vega-Lite grammar, empowers you to spend less time writing code and more time exploring your data.

VegaFusion provides serverside acceleration for the Vega visualization grammar. While not limited to Python, an initial application of VegaFusion is the acceleration of the Vega-Altair Python interface to Vega-Lite.
