D3.js
JavaScript library for binding data to the DOM and drawing fully custom, interactive visualizations with SVG or Canvas.
D3.js is a JavaScript library for producing custom, interactive data visualizations in web browsers using SVG, HTML, and Canvas. Rather than shipping pre-built chart types, D3 provides low-level primitives — scales, axes, shapes, transitions, and force layouts — for binding data directly to DOM elements, which is what gives it its name (Data-Driven Documents). This makes it the most flexible option for bespoke visual designs, at the cost of a steeper learning curve than chart libraries with ready-made components. D3 runs entirely client-side and is commonly paired with React, Vue, or Observable notebooks, which handle rendering lifecycle while D3 computes layout and scales. It remains the foundation many higher-level libraries (Vega-Lite, Nivo, Plotly.js) are themselves built on.
