{"version":"1.0","type":"rich","title":"City of China","description":"This visualization displays a hierarchical tree of Chinese provinces and cities, with Beijing, Shanghai, Hongkong, and several regional groupings as top-level nodes. Leaf nodes such as Guangzhou and Shenzhen are shown with uniform values. The graph uses D3 v5’s `d3.hierarchy` and `d3.tree` to compute node positions, while `d3.linkHorizontal` generates Bézier curves for the links. Nodes are rendered as white circles with blue strokes, and labels are placed beside each circle in an SVG canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ab1cb9cac082450ca141275233333bc9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
