{"version":"1.0","type":"rich","title":"Fork of Radial Tree of Countries Hierarchy","description":"This fork of Curran Kelleher’s radial tree visualizes a hierarchy of world countries, grouped by continent and subregion, with labels placed along circular branches. Users can pan and zoom the entire SVG scene using `d3.zoom` and `d3.event.transform`. The code builds the layout with `d3.cluster` and `d3.hierarchy`, projects nodes via a custom `project` function, and sizes text with `d3.scaleSqrt` based on depth. The underlying data is loaded from `data.json` using `d3.json`.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/dd510ca5820440779f6626f2295bc783?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
