Altair Declarative, Statistical Visualization for Python

on YouTube ↗42m

" summary

A Python library that implements a constrained declarative grammar for tidy, DataFrame‑based plots, guaranteed to emit Vega‑Lite JSON rather than render itself, with a type‑checked API auto‑generated from the Vega‑Lite spec. It plugs into the JavaScript stack (Vega, D3, ipyvega) to render in Jupyter notebooks, supports marks, scales, encodings, and faceting, ships ~70 examples and datasets, and serializes to JSON/HTML/PNG; interactivity (selections, cross‑filtering) is planned.
