{"version":"1.0","type":"rich","title":"Fork of Radial Tree of Countries Hierarchy","description":"This radial tree visualization shows the hierarchical structure of world countries, organized by continent and subregion, with each country as a leaf node. The circle-packing layout positions nodes radially, and the code uses `d3.hierarchy` and `d3.cluster` to compute the layout, with `d3.zoom` enabling pan and zoom interactions on the SVG. Link paths are generated manually via a projection function, and text labels adjust rotation and anchor based on depth and angle, with font size scaled by depth.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8fe39a16baa34121aadf919273e16594?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
