{"version":"1.0","type":"rich","title":"Fork of Radial Tree of Countries Hierarchy","description":"This radial tree visualization displays the hierarchical structure of world countries organized by continent and subregion. The visualization uses a circular layout with connecting bezier curves, where text labels are rotated and positioned according to their depth in the hierarchy. The code implements interactive panning and zooming through `d3.zoom`, while the tree layout is computed using `d3.cluster`. Text sizing scales with depth using `d3.scaleSqrt`, and the SVG rendering includes a glow effect on labels for improved readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/093b47c68ff248339a7413cd5c012796?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
