About Chart.js
Overview Chart.js is an open source HTML5 charting library for the modern web. It provides a simple yet flexible way to create animated, responsive charts using the HTML5 Canvas element. Built for developers who need to visualize data on websites, Chart.js offers 8 chart types with customizable options. Unlike heavier charting libraries, it focuses on performance and ease of use with zero-configuration plugins and tree-shaking for smaller bundle sizes. Key Benefits 8 animated and customisable chart types available out of the box. Great rendering performance across all modern browsers including IE11+. Charts redraw automatically on window resize for perfect scale granularity. JavaScript bundle size can be reduced by dozens of kilobytes through tree-shaking. Transitions of every property in every element can be configured individually. Community maintained project with contributions welcome from anyone. How It Works You include the Chart.js library in your project, create a canvas element in your HTML, then instantiate a new Chart object by passing the canvas context and a configuration object. The configuration object defines the chart type, data, labels, datasets, and any custom options for animations, scales, and plugins. Chart.js renders the chart on the canvas and automatically redraws it on window resize or data changes. Use Cases Web developers building dashboards who need to visualize real-time or static data with animated charts. Data analysts creating interactive reports who want to mix bar and line chart types in a single view. Frontend engineers working on responsive web applications that require charts to redraw on window resize. Open source contributors looking to participate in a community-maintained JavaScript charting project. Educators and students building data visualization projects who need a free, open source library. Why Choose This Product Chart.js is best suited for developers who need a free, open source charting library with good performance across modern browsers. It offers 8 chart types, responsive rendering, and customizable animations without any licensing costs. The library is community maintained and contributions are welcome.
