This example shows an animated family tree for nine individuals, with orange circular nodes labeled by name and connected by lime-green paths. The visualization uses D3 v6’s `d3.stratify()` to build a hierarchy from flat parent–child data and `d3.tree()` to compute node positions. SVG circles and text are appended and animated via `transition()`, with paths drawing between nodes over one second and nodes expanding over 1.5 seconds on a pink background.
