High-performance charts powered by WebGPU

Examples

ChartGPU is a TypeScript charting library built on WebGPU for smooth, interactive rendering—especially when you have lots of data.

Highlights

Architecture

At a high level, ChartGPU.create(...) owns the canvas + WebGPU lifecycle, and delegates render orchestration (layout/scales/data upload/render passes + internal overlays) to the render coordinator. For deeper internal notes, see docs/API.md (especially “Render coordinator”).

Demo

Candlestick Charts

Financial OHLC (open-high-low-close) candlestick rendering with classic/hollow style toggle and color customization.

Quick start

Installation

npm install chartgpu

React Integration

React bindings are available via chartgpu-react:

See the chartgpu-react repository for full documentation and examples.

Browser support (WebGPU required)
