This visualization displays a family tree with nine members across four generations, using colored nodes to distinguish generations and animated links to show parent-child relationships. The tree is built from flat data using `d3.stratify()` and `d3.tree()`, with SVG circles and text labels rendered via React. Paths animate from source to target positions using `transition().duration()`, while node colors are assigned through a custom `setGeneration()` function based on each node’s depth. The layout is computed with d3.v6’s tree utility, and all rendering occurs through SVG elements.
