This interactive family tree visualizes a multi-generational hierarchy using collapsible nodes and animated layout transitions. It shows relationships between individuals like ViplavaKumari, Rambabu, and their descendants, with color-coded node types indicating different generations or branches. Built with D3.js v3, the visualization uses a tree layout to position nodes, SVG rectangles with external HTML foreign objects for labels, and CSS-based tooltips. Clicking a node collapses or expands its subtree, while panning and zooming is enabled through `d3.behavior.zoom`. The tree loads hierarchical data from a JSON file and arranges nodes with animated transitions.
