This example shows an animated family tree built with D3.js v6. It visualizes hierarchical relationships between family members using a tree layout, with nodes as circles colored by generation depth and connected by lime-green links. The data is defined as an array of child-parent pairs, processed with `d3.stratify()` and `d3.tree()`. The SVG rendering animates path connections and circle radii using `transition().duration()`, and labels each node with the child name.
