This example shows a family tree for the Mandava lineage, with three generations of named relatives branching from a single root. The visualization uses a D3.js tree layout (d3.layout.tree) with animated node transitions on click, rendered as SVG. Links appear as pink diagonal strokes, and nodes are styled with colored circles that change fill for highlighted states. The data is hardcoded as a JSON object, and the update function manages enter, update, and exit selections with a 750-millisecond duration.
