{"version":"1.0","type":"rich","title":"Data Tree","description":"This visualization displays a hierarchical data tree representing healthcare spending categories, with nodes for year, totals, age groups, and payment types like out-of-pocket and private insurance. The layout uses d3.tree() to compute node positions, rendering circles for each node and SVG line elements for links between parent and child nodes. Data is loaded asynchronously from a JSON file via fetch(), then processed with d3.hierarchy() to create the tree structure. The visualization fills the entire browser window using dynamically sized SVG dimensions.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fb6e8fcae5634c66a31d44dcd26a2730?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
