{"version":"1.0","type":"rich","title":"Tree","description":"A vertical tree diagram displays three levels of food categories, from the root \"Food\" down to fruits, vegetables, dairy, and their individual items. The SVG visualization uses D3 v7's `d3.stratify` and `d3.tree` layouts, reading hierarchical data from a local `food_tree.json` file. Node circles are colored by depth using a `d3.scaleOrdinal` with blue, orange, and green, while `d3.linkVertical` draws the connecting paths between parent and child nodes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7f44e5c348004279bfd4e37eefbdc0aa?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
