This interactive family tree visualization displays a hierarchical genealogy chart with color-coded nodes representing different family members across four generations. Built with D3.js v3 and SVG, the tree uses a collapsible node layout with animated transitions, allowing users to expand and collapse branches. The data comes from a JSON file structure populated with names and relationship links. The visualization includes zoom and drag capabilities, tooltips, and directional arrows showing parent-child connections, with node colors distinguishing between different types of family relationships.
