{"version":"1.0","type":"rich","title":"RADIAL TREE","description":"A radial tree displays a hierarchy of world countries, organized by continent and subregion, radiating outward from a central root node. The visualization uses an SVG rendering with D3 v4’s `d3.cluster` layout to position nodes, and custom bezier paths for links. Text labels are rotated and sized by depth, with a heavy white glow for readability. Panning and zooming are implemented via `d3.zoom`, while the JSON data structure defines the nested country groupings.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a266098950f947b9a578b3beac418b88?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
