{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This visualization renders the hierarchical structure of world countries as a vertical tree, grouping nations by continent and subregion. It shows the nested relationships between continents, regional divisions, and individual countries. The code uses D3 v5’s `tree` layout and `hierarchy` functions to compute node positions, with `linkVertical` generating curved paths for connections. SVG circles and text labels display each node, while the `zoom` behavior enables panning and scaling. Data is loaded from a JSON file, and styling uses the Playfair Display font with color-coded nodes and links by depth.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/36a2e786dd8747bead03b5d4db9b73d6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
