This visualization arranges plant taxonomy into an interactive, animated tree diagram, using colored, rounded rectangles to represent different classification levels from “plants” down to specific groups like “tulips” and “flowers.” Built with D3.js v3, the layout is computed via `d3.layout.tree`, while SVG elements are manipulated with `d3.select` and standard zoom/pan behaviors. Node colors are assigned by type, and tooltips plus click-to-collapse interactions are included; the diagram loads hierarchical JSON data containing names, links, and direction attributes, with rendering handled primarily through SVG groups, foreignObject for text, and CSS-defined arrow and link styling.
