Datashader — render billions of points without choking
Datashader handles massive datasets that kill matplotlib in seconds, using GPU-accelerated aggregation to turn dense point clouds into interactive visuals. The tutorial walks you through the full pipeline: point clouds, categorical binning, line rendering, raster data, and composite dashboards, all runnable in Colab. Built for analysts and engineers dealing with real-time or archived telemetry, financial tick data, or spatial datasets that scale.
