This interactive family tree visualizes hierarchical relationships among named individuals using a collapsible, animated node-link diagram. The SVG-based visualization uses D3.js v3 with the `d3.layout.tree` API to compute tree layouts, and includes features like color-coded node types (Type1–Type4), zoom and drag behavior, and tooltip interactions. Data is loaded from a JSON file via `d3.json`, and animations are triggered through `d3.behavior.zoom` and node click handlers. The rendering emphasizes clear parent-child links and supports interactive exploration of the genealogy structure.
