{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This visualization displays a hierarchical tree of world countries, organized by continent and subregion, with the root labeled \"World\" and leaf nodes representing individual nations. The layout uses a tidy tree algorithm to position nodes, with horizontal links rendered as smooth curves. The SVG rendering employs D3 v5’s `tree`, `hierarchy`, and `linkHorizontal` methods, while pan and zoom interactions are enabled via the built-in `zoom` behavior. Text labels are sized inversely to node depth, creating a clear visual hierarchy.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9c886da4740442208e5a077e5b89a374?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
