Fork of Animal Kingdom — Taxonomy Tree
This visualization presents the Animal Kingdom as an interactive taxonomic tree, branching from a root through kingdom, class, and order layers down to individual species. Nodes are colored by depth, and hovering reveals tooltips. Built with D3 version 7, it uses `d3.stratify()` to convert a flat parent-child data array into a hierarchy, then `d3.tree()` to compute positions for the SVG rendering. Links and node circles are styled with CSS classes based on depth, and a color legend explains the layer mapping.
