{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This visualization shows a hierarchical tree of world countries, organized from continents down to subregions and individual nations, using a horizontal dendrogram layout. Labels appear at each node, with font size decreasing by depth to emphasize higher-level groupings. The implementation uses D3 v5’s `d3.hierarchy`, `d3.tree`, and `d3.linkHorizontal` to compute the layout and draw SVG paths, while `d3.zoom` enables panning and zooming. Styling relies on a Playfair Display font and teal connection lines, with data loaded from a local JSON file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8648dd3dfb714ee9b7d1addb7fc0a609?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
