## What it is
deck.gl is a GPU-powered (WebGL2/WebGPU) JavaScript framework for high-performance visualization of large datasets, built around composable visual layers and views. It integrates with major basemap providers like Mapbox, MapLibre, Google Maps, and ArcGIS, and offers a Python binding (pydeck).

## Use cases
- visualize millions of points on an interactive map
- render geospatial data with hexbin or heatmap aggregation layers
- build a React dashboard with large-scale data overlays
- visualize 3D point clouds and terrain data in the browser
- create trip and arc visualizations for movement data
- explore large datasets with GPU-accelerated charts from Python via pydeck

## When to choose
- you need performant rendering of very large datasets in the browser
- you are building geospatial or map-based visualizations with basemap integration
- you want a composable, extensible layer architecture with React support

## When to avoid
- you only need simple static charts or plots
- your project targets environments without WebGL/WebGPU support
- you need server-side rendering of visualizations

## Facets
- artifact type: framework
