This example shows a static, branching tree diagram of the animal kingdom, organizing species into a hierarchical structure from "Animals" down to specific classes like Mammals, Birds, and Insects. The visualization uses a collapsible node-and-link layout, where each node is a circle with a text label, and the connections are curved paths. Built with the D3.js library (version 3.5.17), the code defines the tree data as a JSON object and uses `d3.layout.tree` for positioning and `d3.svg.diagonal` to draw the connecting curves. The SVG canvas is generated directly in the HTML page, with node styling and colors specified via CSS classes.
