{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This visualization displays a hierarchical tree of world countries, organized by continent and subregion, using a horizontal icicle layout. The interactive SVG graphic uses D3 v5's `tree()` layout, `hierarchy()`, and `linkHorizontal()` to draw the branching structure, with country names plotted as text nodes. Font size decreases with tree depth, and the entire view supports zooming via the `zoom()` event handler. Data comes from a JSON file containing the nested geographic groupings.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/16b9f2123bcc4c5592d1490cdb97ebbc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
