What Chart.js does

Chart.js is an open-source JavaScript/TypeScript charting library, founded in 2013, that provides web developers with eight chart types — line, bar, radar, doughnut, pie, polar area, bubble, and scatter — rendered via HTML5 Canvas for cross-browser performance including IE11+. The library includes built-in animations, responsive resizing, tree-shaking support (reducing bundle size from approximately 48 KB to 14 KB in v4.0), and a plugin ecosystem covering decimation, subtitle, title, tooltip, legend, filler, and a default color palette.

The product is distributed through three parallel channels — GitHub for source and releases, npm for package installation, and CDN for script-tag inclusion — and integrates with plain JavaScript as well as module loaders including Webpack, Rollup, CommonJS, and RequireJS. Community-maintained framework adapters for React, Angular, and Vue are listed in the project's official Awesome ecosystem repository.

Chart.js operates as a community-maintained open-source project with no commercial entity, no paid product tiers, no pricing model, no disclosed headcount, and no institutional funding. The project follows a pure product-led growth motion: developer adoption is driven through documentation quality, GitHub discoverability, and community word-of-mouth via Discord and Stack Overflow, with no formal sales organization. The single defined customer segment is web developers building data visualization for dashboards, reports, and analytics interfaces, served on a global basis with no geographic restrictions.
