{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This interactive visualization displays a hierarchical tree of world countries, organized by continent and subregion, with labels sized by depth. The hierarchical data comes from a JSON file, and the layout is computed using D3’s `tree` and `hierarchy` functions. Links are drawn as horizontal curves via `linkHorizontal`, while text nodes are placed according to the tree’s coordinates. The SVG rendering uses D3 v5, with styles defined in CSS.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7277c09bd4184878ba86e4e0590933a4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
