{"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. It uses a D3 tree layout with horizontal links to show the parent-child relationships between geographic groupings, from \"World\" down to individual nations. The text labels are sized according to depth, with shallower nodes appearing larger. The implementation uses D3 v5’s `tree`, `hierarchy`, and `linkHorizontal` functions to compute the layout and link paths, while a zoom behavior allows panning and scaling of the SVG rendering.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c3c479aec98349e08ee79a929c95d2bb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
