D3.js

D3.js (Data-Driven Documents) is a JavaScript library for creating dynamic, interactive data visualizations in web browsers. It uses web standards like HTML, SVG, and CSS to bind data to DOM elements, enabling developers to manipulate documents based on data. It is widely used for building complex charts, graphs, maps, and dashboards.

Also known as: D3, Data-Driven Documents, D3JS, D3js, d3

Why learn D3.js?

Developers should learn D3.js when they need to create custom, data-rich visualizations that go beyond basic charting libraries, such as for scientific data, financial dashboards, or interactive infographics. It is particularly valuable for projects requiring fine-grained control over visual elements, animations, and user interactions, as it provides low-level APIs for direct DOM manipulation.
