{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This tree visualization maps the hierarchical structure of world countries, grouping them by continent and subregion. The data, loaded from a JSON file, is rendered as an indented tree with connecting paths, where each node's font size decreases with depth. The visualization uses D3's `tree` layout, `hierarchy` for data structuring, and `linkHorizontal` for path generation, all rendered as SVG within a zoomable interface.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/7dafad9cef3c43fc99145c7a282659dd?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
