This interactive family tree visualization displays a genealogical hierarchy based on the Bodapati family data, showing three generations of descendants from a single ancestor. The tree layout uses collapsible nodes, where clicking a node toggles the visibility of its children. Built with D3.js version 3.5, the visualization employs the `d3.layout.tree` for hierarchical positioning and `d3.svg.diagonal` for the curved links between nodes. SVG elements render the nodes and text, with CSS styling for colors and fonts, while animated transitions (750ms duration) smoothly move nodes between expanded and collapsed states.
