A phylogenetic tree visualization presents the evolutionary relationships among organisms, arranged radially with colored branches distinguishing major domains such as Bacteria, Eukaryota, and Archaea. The interactive chart allows users to toggle branch length display with a smooth animated transition. Built with D3.js, it uses hierarchical clustering to position nodes, SVG rendering for scalable graphics, and transition animations to update paths smoothly. Mouseover interactions highlight the lineage from a leaf back to the root. The data originates from a Newick-format phylogenetic tree file.
