{"version":"1.0","type":"rich","title":"Untitled","description":"This radial dendrogram visualizes a hierarchical dataset of world countries organized by continent and subregion, using D3 v4’s `d3.cluster` layout to position nodes in circular coordinates. Text labels for all nodes are rendered with SVG, with font sizes scaled by depth via `d3.scaleSqrt` and rotated or flattened based on angular position for legibility. The visualization supports zooming and panning through D3’s `d3.zoom` behavior, which applies a transform to the containing group. Links are drawn as curved paths, with straight segments connecting top-level regions directly to the root.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ba2fcfe9c7874fd686d39ae88a72eb0f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
