{"version":"1.0","type":"rich","title":"Fork of ICE-8 Tree graph","description":"This example shows a hierarchical tree graph of hospital emergency room data, organized by category and hospital, with nested nodes for location and bed count. The visualization uses D3.js v7 with an SVG renderer, applying a tree layout with horizontal links and distinct node shapes—ellipses, rectangles, and circles—based on depth. Data is loaded from an external CSV file via d3.csv, and the tree structure is built and rendered using d3.hierarchy and d3.tree().","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d992695aa9a947419cdfdf4aadbc8159?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
