{"version":"1.0","type":"rich","title":"Tree","description":"A D3.js (v7) SVG tree diagram displays the hierarchical structure of US regions and states, with a root node for the United States branching into color-coded Central, Western, and Southern region nodes, each containing leaf state nodes. The layout is computed using `d3.tree()` with `d3.hierarchy()`, while links are drawn as horizontal paths via `d3.linkHorizontal()`. Nodes appear as circles with region colors or white for states, and labels are placed using `text-anchor` based on branch direction. The data is static JSON embedded in the script, rendered with a light background and sans-serif typography.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b6666f6c7a8a48398f722c2986c7b791?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
