{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This visualization shows a hierarchical tree of world countries organized by continent and subregion, with each node labeled and connected by curved links. It uses D3 v5’s `tree` layout and `hierarchy` to structure the data, rendering SVG paths via `linkHorizontal` and text labels with font sizes scaled by depth. The view supports zooming through D3’s `zoom` behavior, and the data comes from a local `data.json` file containing nested geographic groupings.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c18fa35c3dd54519896ac0dac398a87c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
