{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This radial tree visualization displays hierarchical data from the `flare` dataset, with nodes positioned in a circular layout and connected by curved links. D3's `tree` layout and `stratify` function compute node positions and hierarchy, while `project` converts coordinates to a polar system. The SVG rendering includes zoom and pan support via `d3.zoom`, and text labels rotate to follow the circular structure.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4988f9024b4a4a8fb0407f641f7afd52?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
