{"version":"1.0","type":"rich","title":"Fork of Tree graph","description":"This example visualizes a restaurant business hierarchy as a tree graph, with nodes representing categories like Location, Cuisine Type, and Price Range, each branching into specific subcategories. Node size encodes a numeric value, while stroke and fill colors differentiate types and levels. The code uses D3 v5’s `d3.tree()` and `d3.hierarchy()` to compute layout, rendering SVG paths for links and circles for nodes. Data is hardcoded in JavaScript, with styling applied via CSS classes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6334335529a4427982d641bbda9311ef?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
