{"version":"1.0","type":"rich","title":"World Countries Hierarchy","description":"A hierarchical tree visualization displays the world's countries organized by continent and subregion. The visualization uses D3 v5's `tree` layout with `linkHorizontal` paths to connect parent and child nodes. Text labels for each country are positioned according to the layout's x and y coordinates, with font sizes scaling logarithmically based on depth. The SVG rendering supports zooming and panning through D3's zoom behavior, and the data originates from a JSON file containing the nested geographic hierarchy.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4c342cf90eb4458c8b30c0ed52e26b6b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
