This interactive family tree visualization displays a hierarchical genealogy chart rooted at Sammaiah, with branches extending to children and grandchildren. The tree uses color-coded nodes by generation type and animated expanding/collapsing interactions. Built with D3.js v3, it implements a custom `d3.layout.tree()` for positioning, with SVG rendering for nodes and links. The visualization includes tooltips, zoom and drag behavior, and transition animations. Node data comes from a JSON file, with CSS styling handling visual properties like node appearance, link strokes, and hover states.
