{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This visualization presents the hierarchical structure of world countries, organized by continent and subregion, as a horizontal tree diagram. The layout uses a D3 tree layout with data loaded from a JSON file, rendering nodes as text labels and connections as curved paths via `linkHorizontal`. The view supports pan and zoom through D3’s zoom behavior. Styling relies on SVG elements, with font sizes varying by depth and a custom serif typeface.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0f26b2c82d254541b770ed30076184fa?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
