A fork of a fork of a fork animates a branching tree structure that continuously splits and grows across the screen. Using D3 v7’s `d3.forceSimulation`, the code computes node and link positions for a dynamically expanding network, with each branch spawning new child nodes over time. The SVG rendering updates via D3’s data join and transition methods, while `d3.zoom` and `d3.drag` handle pan, zoom, and node interaction. The example is fully self-contained, generating its data procedurally from a random walk rather than loading external datasets.
