This interactive animal tree visualization displays a hierarchical dataset of dog breeds, from the root "Dog Breed" down through subcategories like Retriever, Bull Dog, and Poodle to specific breeds such as Golden Retriever and French BullDog. Built with React and rendered as animated SVG, the diagram uses D3.js libraries including `d3.layout.tree` for tree layout, `d3.svg.diagonal` for link projections, and D3 transitions to animate node expansion and collapse. Clicking nodes triggers smooth animated updates, with nodes and links styled via CSS attributes like purple circles and red strokes.
