This interactive family tree visualizes the evolutionary hierarchy of Homo sapiens, from Hominoidea down to the genera Homo and Pan. Built with D3.js, the SVG diagram uses a collapsible tree layout with animated transitions for expanding and collapsing nodes. Clicking a node toggles its children, while links and circles are rendered using D3’s `d3.layout.tree` and `d3.svg.diagonal`. The data is hardcoded in JavaScript, and the styling uses custom CSS for node and link appearance.
