{"version":"1.0","type":"rich","title":"Fork of Radial Tree of Countries Hierarchy","description":"This radial tree visualization displays a hierarchical breakdown of world countries organized by continent and subregion, with each node labeled at its corresponding depth level. The visualization supports panning and zooming through the `d3.zoom` API, which applies transforms to the SVG group element. The code uses `d3.cluster()` to compute node positions in a circular layout and `d3.scaleSqrt` to size the text based on tree depth. Links draw as curved paths for deeper nodes, while leaf nodes align text to the outer edge for readability. The data originates from a JSON file containing the full country hierarchy.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d610a5d352004cbb98c201c17fb66cad?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
