2D layout algorithms for visualizing hierarchical data.

Encodings that map abstract data to visual representation.

Force-directed graph layout using velocity Verlet integration.

Geographic projections, spherical shapes and spherical trigonometry.

Graphical primitives for visualization, such as lines and areas.

Array manipulation, ordering, searching, summarizing, etc.

Select a one- or two-dimensional region using the mouse or touch.

Drag and drop SVG, HTML or Canvas using mouse or touch input.

Transform the DOM by selecting elements and joining to data.

Parse and format times, inspired by strptime and strftime.

Animated transitions for D3 selections.

Human-readable reference marks for scales.

Visualizations relationships or network flow with a circular layout.

Color spaces! RGB, HSL, Cubehelix, CIELAB, and more.

Easing functions for smooth animation.

Interpolate numbers, colors, strings, arrays, objects, whatever!

Register named callbacks and call them with arguments.

Serialize Canvas path commands to SVG.

An efficient queue for managing thousands of concurrent animations.

Evaluate asynchronous tasks with configurable concurrency.

Force-directed graph layout using true velocity Verlet integration for use in molecular dynamics.
