{"version":"1.0","type":"rich","title":"Tree","description":"This example visualizes the hierarchical structure of Xinjiang’s administrative divisions and their populations using a vertical tree layout. Each node is a circle colored by its top-level prefecture, with links drawn via `d3.linkVertical` and text labels rotated vertically. The code uses `d3.hierarchy` and `d3.tree` to compute positions, `d3.scaleOrdinal` with `d3.schemeCategory10` for colors, and renders output as SVG. Population data comes from the embedded `xinjiang.json` file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/82e8b0fc0983482a87143fb8891cfb5c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
