{"version":"1.0","type":"rich","title":"Fork of Radial Tree of Countries Hierarchy","description":"A radial tree shows the hierarchical organization of countries by continent and subregion, branching outward from a central \"World\" root. D3’s cluster layout computes angular and radial positions, while SVG paths connect parent-child nodes. Panning and zooming are enabled via d3.zoom. Node labels use hue-free teal links and font sizes scaled by depth, with text rotation applied for deep leaves. Data comes from a JSON hierarchy.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0ee5a0d92df54c1699346e235b7c6e8a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
