This fork of a family tree visualization uses D3 v6 to display hierarchical relationships among a set of characters. The D3 `stratify()` API constructs the tree structure from parent-child links, while `d3.tree()` calculates the layout. Nodes are rendered as colored SVG circles, with colors indicating generation depth, and are animated via D3's `transition()` API. The connections between nodes are drawn as lime-green paths. The embedded text labels are placed directly on each circle using SVG text elements.
