This interactive family tree visualization displays hierarchical relationships between named individuals, with color-coded nodes indicating different family types. The tree renders as an SVG using D3 v3's tree layout and includes pan-and-zoom functionality through d3.behavior.zoom. Nodes are clickable and expand or collapse their children with animated transitions. The data comes from a JSON file, and the implementation uses jQuery alongside D3 for DOM manipulation, styling nodes, links, and tooltips with custom CSS classes.
