{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This interactive visualization displays the hierarchical structure of world countries, organized by continent and subregion, using a horizontal tree layout. It loads country data from a JSON file and renders it as an SVG with D3’s `tree` and `hierarchy` functions, connecting nodes with `linkHorizontal` paths. Text labels scale in font size by depth, and the entire view can be panned and zoomed via D3’s `zoom` handler applied to a group element.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0303b877fc9b4d309b40bc26ae2d59fa?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
