{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This visualization shows a hierarchical tree of world countries organized by continent and subregion, with country names displayed at varying font sizes based on depth. The tree layout uses d3.tree with a horizontal link generator (d3.linkHorizontal) to connect parent and child nodes, while d3.zoom enables panning and zooming of the SVG rendering. The data, loaded from a JSON file via d3.json, contains nested geographic groupings, and the text nodes are positioned along the computed tree coordinates with depth-based font scaling.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2206ad72459f47ff941b519b2764ce48?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
