This example presents a branching family tree using an animated SVG diagram. Nodes are rendered as yellow circles with black outlines, connected by maroon lines to show parent-child relationships. The visualization uses D3.js v6 with the `d3.stratify()` and `d3.tree()` APIs to structure the data, and `transition()` for animated draws. Node names appear as text labels, with the graph centered on the page. The underlying data is a hardcoded list of names representing family members and their lineage.
