A family tree displays six names across four generations as colored circles connected by green paths. The visualization uses d3.stratify() to structure hierarchical data and d3.tree() to compute node positions in a 600-by-300 layout. Each generation receives a distinct color via a switch function, with nodes rendered as SVG circles and text labels. Paths animate from source to target using transition().duration(1500), while circles grow into place over 700 milliseconds. The SVG scales to the full window size, and all elements are positioned within a translated group.
