UrChartsYour charts, GPU-fast.

Framework-agnostic, GPU-accelerated TypeScript charting for financial and big-data visualization on the web.

D3 for math

d3-scale, d3-array, d3-time, d3-format compute scales, ticks, formatters. D3 never touches geometry.

WebGL2 today, WebGPU-ready. SDF lines, areas, splines, bars, candles, OHLC — all GPU-instanced.

Axes, labels, gridlines, legends, tooltips stay in SVG/HTML — free font hinting, a11y, copy-paste.

Every visual capability is a plugin. The kernel is tiny. Third-party plugins are not second-class.

Ships as a Web Component (``). React / Vue / Svelte wrappers are thin shims.

Delta protocol (append / replace / invalidate) and a Float32Array RingBuffer. Built for live ticks.
