{"version":"1.0","type":"rich","title":"Fork of Radial Tree of Countries Hierarchy","description":"This full-circle radial tree displays a hierarchical breakdown of world countries by continent and subregion, using a JSON dataset. The visualization supports panning and zooming through D3’s `d3.zoom` event handler. The layout is computed with `d3.cluster()` in a 360-degree arrangement, with curved link paths and nodes rendered as SVG circles. Text labels rotate radially to follow branch angles, with font size scaled by depth using `d3.scaleSqrt`. Distinct stroke colors and dash patterns differentiate hierarchy levels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2250ee48e9f445bdb99db40f715d0346?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
