Declarative Python library for building charts from a Vega-Lite specification.
altair-viz.github.io/repositorydocs
Vega-Altair is a declarative visualization library for Python, built on the Vega-Lite grammar. The installation guide installs it with pip.
Saving a chart to an HTML file creates a page that loads Vega, Vega-Lite and vegaEmbed, and the chart renders when a browser opens that page. The project is maintained by Vega-Altair Developers.
