This example visualizes a family tree using a hierarchical layout, with nodes representing individuals and links showing parent-child relationships. Rectangular nodes with names animate into position, and connecting paths draw from parent to child. The visualization is rendered as SVG using D3 v6, employing `d3.stratify()` to structure the flat data and `d3.tree()` to compute positions. Transitions animate the paths and text, with staggered delays based on node depth.
