HoloViz: Visualization and Interactive Dashboards in Python

on YouTube ↗29m

" summary

HoloViz presents a layered Python stack: a data-centric plotting API (hvPlot) that attaches plotting methods to pandas/xarray/geopandas, a rasterizer (DataShader) that renders millions-to-billions of points server-side so only screen pixels transfer, and a dashboard framework (Panel) that wires widgets to plots and deploys via panel serve. Examples include a 213,000-glacier map, ~918,000-flight visualization, exoplanet and ship-traffic apps. Notes: Panel 1.0 uses Bokeh backend; Pyodide/PyScript enable client-side apps but DataShader lacks WebAssembly support.
