{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This tree diagram shows the hierarchical structure of world countries, organized by continent and subregion. The visualization uses a horizontal icicle layout where the root node \"World\" branches into continents like Asia, which further divide into regions and individual countries. The hierarchical data is loaded from a JSON file and rendered with D3 v5, using the `tree()` layout function to compute node positions and `linkHorizontal()` to generate the connecting paths. Pan and zoom functionality is enabled through D3's `zoom()` event handler, which transforms the SVG group containing the entire tree.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/27b0ea7f41bb4f309c3f60b166da773b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
