{"version":"1.0","type":"rich","title":"World Tree","description":"The World Tree visualization displays a hierarchical dataset of global regions and countries as a radial tree diagram. It uses D3’s `tree` layout and `hierarchy` function to compute node positions, with SVG `path` elements representing the links between parent and child nodes. The interactive chart is built with D3 v5 within a React framework, using `json()` to load the data and `select()` to manage the SVG canvas. Text labels are styled with a serif font and white text shadow for readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7893184f63274c81a9353246ad5a19f0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
