This interactive family tree visualizes genealogical connections using a parent-child hierarchy. Built with D3.js v3, it renders the structure as an SVG diagram with rectangular nodes and labeled links, supporting zoom and drag interactions. The data from `family-data.json` is loaded via `d3.json()`, and the layout is computed using `d3.layout.tree()`. Node colors vary by type, and each node includes a link label with directional information.
