This visualization displays the Naruto clan lineage as a tree diagram, with each node represented by a colored circle and text label. The hierarchical structure uses `d3.stratify()` to convert the flat dataset into a hierarchy, then `d3.tree()` to compute the layout. SVG paths animate from each parent to its child, while circles transition in size and fill color based on generation depth. The code employs d3 v6 with transitions for the connections and nodes, rendering all elements in SVG.
