This visualization displays a family tree as a horizontal dendrogram, with nodes labeled by name and connected by curved links. The layout is generated using D3’s `tree()` layout applied to a hierarchical JSON structure, while `linkHorizontal()` creates the paths. Rendering uses SVG within a zoomable group, enabled by `d3.zoom`, which applies pan-and-zoom transforms to the entire tree. Text size scales with node depth, and all data comes from `data.json`.
