{"version":"1.0","type":"rich","title":"Fork of Radial Tree of Countries Hierarchy","description":"This radial tree visualization displays a hierarchical breakdown of world countries by continent and subregion, with each node labeled by name and scaled by depth. The layout uses a D3 cluster layout, projecting nodes in a circular arrangement from a central root. Users can pan and zoom the SVG canvas via d3.zoom. The data, loaded from a JSON file, is structured hierarchically, and the code adapts Curran Kelleher’s original block by adjusting link paths and text rotation for readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e1e384b133fa49b6a1fb979b091c6f0d?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
