This example shows a hierarchical family tree as an animated SVG graphic, with nodes represented by salmon-colored circles and connecting paths drawn as blue lines. The visualization uses D3 v6’s `d3.stratify` to convert a flat array of parent-child data into a hierarchy, then applies `d3.tree` to compute node positions. Initially, all nodes appear as circles at their parent’s location, and paths animate outward from each parent to its children over one second. Text labels fade in sequentially based on tree depth, using chained transitions with a delay proportional to each node’s depth.
