Composable forces
Links, charge, collision, centering, radial targets, custom gravity, boundaries, and pointer fields.
D3 Laboratory
Graphs that behave like worlds.
Eight experiments built from one force engine: explore the network, bend its physics, paint gravity, trace signals, and watch the same data become completely different systems.
Interactive simulation gallery
Living graph
Zoomable network with semantic labels, neighbor focus, animated edge traffic, dragging, and group selection.
0 nodes 0 links 1.0× zoom
Direct manipulation
Node dragging, group dragging, panning, zooming, lasso selection, hover focus, and click-driven state.
Data that moves
Layout morphs, traveling edge particles, BFS cascades, path animation, shockwaves, and persistent trails.
Derived structure
Convex community hulls, curved edges, neighborhood emphasis, shortest paths, and semantic zoom labels.
