ChartGPU: WebGPU-Powered Charts That Hold Up at a Million Points
A WebGPU charting library that pans and zooms a million points without blinking. LTTB downsampling runs as a compute shader, hit-testing is GPU-accelerated, and each series ships as a single instanced draw. Line, area, bar, scatter, pie, candlestick. 97% TypeScript, 3% WGSL, MIT-licensed.
