{"version":"1.0","type":"rich","title":"Fork of Radial Tree of Countries Hierarchy","description":"This radial tree visualizes the hierarchical relationships between world regions and their constituent countries. The data is loaded from a local JSON file and rendered as an SVG, with the root node placed at the center and branches extending outward. The visualization supports panning and zooming interactions through `d3.zoom`, allowing users to explore the hierarchy at different scales. Node labels are rotated and positioned based on their depth and angle, with font size scaling according to hierarchy level. The implementation builds on the `d3.cluster`, `d3.hierarchy`, and `d3.scaleSqrt` APIs.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3374f337ddc74828b98018b7d6546dc0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
