This fork of a tree visualization displays a biological taxonomy hierarchy, showing the classification of living organisms from the kingdom level (Animalia) down to specific species like Lion, Eagle, and Octopus. The diagram uses colored nodes and connecting links to distinguish four taxonomic layers: Kingdom, Phylum, Class, and Species, with a legend explaining the color coding. Built with D3 v7, the visualization constructs the hierarchy from a flat list of parent-child relationships using `d3.stratify`, then renders the result as an SVG tree with labeled circular nodes. The HTML page includes a styled chart container and a color legend, presenting the data vertically with a viewBox of 1000 by 800 pixels.
