This interactive tree chart displays a family lineage, starting with Peddi Kumara and branching through multiple generations of children and grandchildren. Rendered as an animated SVG using the D3.js library (version 3.5.17) and its `d3.layout.tree` and `d3.svg.diagonal` APIs, the visualization lets users click on nodes to expand or collapse subtrees. The cyan and red circular nodes with blue connecting links are styled via CSS, and the tree is laid out vertically with a dark orange page background.
