About the project

HighScale Chart is a performance-first charting library — a WebGL renderer with LTTB + min-max downsampling keeps millions of points smooth at 55+ FPS in a tiny bundle. It offers TanStack-like DX and is organized as a pnpm monorepo (packages/core + apps/benchmark) with a real benchmark gate.
