{"version":"1.0","type":"rich","title":"Fork of Radial Tree of Countries Hierarchy","description":"This radial tree visualization displays a hierarchical dataset of world countries organized by continent and subregion. The graph uses curved links and rotated text labels to show the nested structure, with font size scaling by depth level. Built with D3 v4, it utilizes `d3.cluster`, `d3.hierarchy`, and `d3.zoom` for layout and interaction. Panning and zooming are enabled through the zoom module, which applies transformations to the SVG group. The data comes from a local `data.json` file containing the geographic hierarchy.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c8f90cfff94e4f73a5fc626a3e7a3627?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
