{"version":"1.0","type":"rich","title":"World countries tree","description":"This example shows a hierarchical tree of world countries, organized by continent and subregion, using a tidy tree layout. The visualization uses a horizontal dendrogram where nodes are labeled with country names, and links are drawn with D3's `linkHorizontal` path generator. The code imports functions like `tree`, `hierarchy`, and `zoom` from the `d3` module, and loads data from a JSON file. Text styling includes a custom Spirax font and white text shadow for readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/102b21d25b83429f83674bbd749273dd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
