Billboard.js
billboard.js is a JavaScript charting library built on D3.js that renders interactive data visualizations from a single declarative configuration object. It supports a wide range of chart types including bar, line, pie, scatter, area, spline, step, candlestick, funnel, gauge, heatmap, radar, polar, treemap, bubble, donut, and sparkline charts, and can overlay multiple chart types within a single visualization. The library offers an opt-in Canvas rendering mode for improved performance with large datasets and high-density axis displays, alongside its standard SVG-based rendering.
The library distinguishes itself through a modular, tree-shakeable architecture that allows importing only the chart types and interaction modules needed, reducing final bundle size. It provides dedicated component wrappers for React, Vue.js, Svelte, Angular, and other frameworks, as well as standard web components, enabling declarative use across different environments. A plugin extension interface allows third-party features to hook into the chart lifecycle, and a CSS-based theming system with pre-built themes like dark and Datalab enables visual customization without touching the rendering engine.
Additional capabilities include interactive features such as zooming, panning, subchart navigation, and data point selection, along with chart image export for both browser and Node.js environments. The library supports multiple independent Y-axes for comparing data series with different scales, logarithmic axis scaling, and data flow animation for smooth transitions when data is updated. Performance optimizations include minimal DOM node generation, axis rendering optimization, and the ability to offload data computation to a Web Worker.
