{"version":"1.0","type":"rich","title":"World Countries Hierarchy","description":"This example visualizes the hierarchical structure of world countries, organized by continent and subregion, using a static tree layout with horizontal links. The SVG rendering uses D3 v5’s `hierarchy` and `tree` layouts, with `linkHorizontal` for the connecting paths. Node labels are sized proportionally to their depth in the hierarchy, and circles mark each country or region. The visualization supports zooming and panning through D3’s `zoom` behavior. Data is loaded from a local `data.json` file containing the nested geographic classification.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d6e56afeef304d35accc23bf796cf519?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
