Flotr2 is a JavaScript charting library that renders graphs and charts (line, bar, pie, etc.) on HTML5 Canvas. It features a modular plugin-based architecture with extensible graph types and a simple draw API.

Use cases

• draw line charts in the browser with canvas
• render pie and bar charts in JavaScript
• add interactive charts to a web page
• visualize data series with axes and gridlines
• embed lightweight canvas graphs without heavy dependencies

When to choose

• you need lightweight canvas-based charts with no large framework dependency
• you want a simple draw API with extensible plugins and graph types
• you need classic chart types like line, bar, and pie in vanilla JavaScript

When to avoid

• you need modern SVG rendering or React/Vue integration
• you require extensive chart types like heatmaps, treemaps, or 3D charts
• you want a library with frequent updates and a large active community
