A family tree visualization maps ten individuals across four generations, using colored circular nodes to distinguish each depth level and labeled text for names. The hierarchical data is structured with `d3.stratify` and laid out with `d3.tree`, producing curved bezier paths via SVG path elements. Node colors switch through a depth-based palette, while the light green background and manual `translate` offset frame the 900-by-900 pixel SVG canvas rendered with D3 v5.
