A family tree visualization presents hierarchical relationships among members of the Peddi family, rendered as an animated, collapsible tree diagram. The chart uses D3.js version 3.5.17 with the `d3.layout.tree` for layout and `d3.svg.diagonal` for curved links between nodes. Each person appears as a cyan circle with red borders and a name label; clicking a node toggles the visibility of its children. The visualization loads data from an embedded JavaScript array and displays it via SVG elements with CSS styling. The page includes an orange background and a centered title.
