Chart.js
Lightweight JavaScript library for the common chart types (bar, line, pie, radar) rendered on HTML5 Canvas.
Chart.js is a JavaScript charting library focused on the small set of chart types most dashboards actually need — bar, line, pie, doughnut, radar, and scatter — rendered on HTML5 Canvas rather than SVG, which keeps it fast and lightweight even with a moderate number of data points. Configuration is a single JavaScript object describing datasets, axes, and styling, with built-in animation and responsive resizing. It has no dependency on D3 or a larger visualization stack, which makes it a common default for teams that want charts in a web app without adopting a heavier library. Community wrappers (react-chartjs-2, vue-chartjs, ng2-charts) cover the major front-end frameworks, and a plugin ecosystem adds chart types such as treemaps and financial candlesticks.
