Documentation

D4 brings to the Dart language and Flutter ecosystem all the power of D3 (or D3.js) — a free, open-source JavaScript library for data visualization. D4 offers a suite of low-level tool libraries that enable the creation of data-driven documents, connecting Dart and HTML, as well as dynamic and interactive visualizations for multiplatform Flutter applications — mobile, web, desktop, and embedded — from a single codebase.
