{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This visualization shows the hierarchical structure of world countries, organized by continent and subregion, as a horizontal tree layout with text labels sized by depth. It renders the data using D3 v5’s `tree()` layout and `hierarchy()` function, with curved links drawn via `linkHorizontal` paths. The SVG scene supports zooming and panning through D3’s `zoom()` behavior. Node labels are styled with CSS text shadows and a Playfair Display font, using data from the local `data.json` file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2be449bc6804498a9571c03d035195c8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
