About D3.js
D3.js is a JavaScript library for creating custom dynamic data visualizations. It provides tools for creating, updating and animating DOM elements based on data, encoding data with scales and axes, rendering geometric shapes, and adding interactions such as panning, zooming, brushing and dragging.
It also includes layout algorithms for treemaps, trees, force-directed graphs and other structures, geographic projections with clipping, and utilities for CSV parsing, date parsing and formatting, color, and statistics. The D3 team also builds Observable Plot, a high-level API for quick charts built on top of D3.
