{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This visualization displays a hierarchical tree of world countries, organized by continent and subregion. The code uses D3.js version 6 to load a JSON data file, compute a tree layout, and render the connections between nodes as horizontal links using SVG paths. The implementation relies on D3's `tree`, `hierarchy`, and `linkHorizontal` functions to generate and draw the structure onto a full-window SVG canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3b5850d430e84f88a8d1f119f7434690?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
