{"version":"1.0","type":"rich","title":"Tree Visualization","description":"This visualization presents a hierarchical tree diagram of animal categories, showing the branching structure from a root \"Animals\" node down to leaf species. It uses D3 v6’s `d3.hierarchy` and `d3.tree` layouts to compute positions, rendering SVG paths for links via `d3.linkHorizontal` and circles with text labels for nodes. The code colors nodes by depth (black for root, blue for internal, green for leaves) within a hardcoded dataset of mammals, birds, and reptiles.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/75667a28f45c407cad14da1ee3a60697?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
