## What it is
ChartGPU is an MIT-licensed TypeScript charting library that renders charts entirely with WebGPU instead of Canvas 2D or SVG. It targets large datasets, real-time streaming appends, multi-chart dashboards sharing one GPU device, and 3D series, with no WebGL/Canvas fallback.

## Use cases
- render million-point scatter plots in the browser
- build streaming real-time dashboards with many charts
- plot candlestick and OHLC financial charts
- visualize high-rate time series without dropped frames
- render 3D point clouds and surfaces on the web
- create heatmaps and spectrogram-style visualizations

## When to choose
- you need to chart hundreds of thousands to millions of points smoothly
- you are building observability, trading, or scientific dashboards with many synchronized charts
- your target browsers support WebGPU (Chrome/Edge 113+, Safari 18+)
- you want GPU-side sampling, density binning, and streaming appends with capped memory

## When to avoid
- you need broad browser support including older Firefox or WebGL/Canvas fallback
- you only need simple static charts with modest data sizes
- your users are on devices without WebGPU-capable GPUs
