SwiftChart bundle size is measured from this repo’s dist/esm/index.js at the current commit. Other libraries’ figures are approximate min+gzip values from bundlephobia for their current major versions; check the live numbers there for precision.
Schema-agnostic
Pass any data shape. Auto-detect fields, or map them explicitly - no rigid schema required.
4 themes built-in
midnight, arctic, ember, forest - or define your own with addTheme().
Animated by default
Easings, durations, and transitions tuned out of the box. Disable with animate: false.
Performance-first
LTTB downsampling, viewport culling, quadtree hover, and offscreen rendering - included.
Production-ready
545+ tests, strict TypeScript, ESM + CJS dual-package, attw + publint clean.
