{"version":"1.0","type":"rich","title":"USA with States Texas and Maryland","description":"This dendrogram-style tree visualization displays a hierarchical structure of the USA, branching into Texas and Maryland, with each state’s major cities as leaf nodes. Node size reflects each element’s `value`, while stroke and fill colors encode `type` and `level` attributes. Built with D3 v5 and rendered as SVG, it uses `d3.hierarchy` to process the nested data and `d3.tree` to compute layouts. Links are drawn as curved paths with colors from `level`, and nodes are positioned via the tree’s `x` and `y` coordinates.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b56fc8176f1345e7b11cd03d38c13167?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
