This interactive tree map visualizes a phylogenetic tree of life, showing the hierarchical relationships among Bacteria, Archaea, and Eukarya down to specific species. Built with D3.js version 3.5, it uses `d3.layout.tree` to compute node positions and `d3.svg.diagonal` to draw curved links between generations. Users can expand or collapse branches through click interactions, with smooth animations updating the SVG layout. The dataset is embedded as a JavaScript array, with nodes colored by taxonomic level, and node styling defined via CSS.
