Chart.ts vs D3.js
D3 is the gold standard for custom data visualizations. It is incredibly powerful but has a steep learning curve and requires building everything from primitives.
| Feature | Chart.ts | D3 |
|---|---|---|
| Bundle size | <15kb min+gzip (entire library) | ~30kb min+gzip (core) |
| Tree-shaking | Full (import only what you use) | Good (modular packages) |
| TypeScript | Built-in, strict mode, full inference | Community types |
| SSR | Native SSR, works with any framework | Requires jsdom or similar |
| Accessibility | WCAG AA, keyboard nav, screen readers, pattern fills | Manual implementation required |
| Tailwind CSS | Native className on every element, dark: variants | Manual (you build the DOM yourself) |
| Chart types | 40+ built-in | Unlimited (build your own) |
| Frameworks | React, Vue, Svelte, Solid, Angular, Vanilla JS | Framework-agnostic (manual DOM) |
