{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This visualization displays a hierarchical tree of world countries organized by geographic regions, rendered as an SVG using d3.v5. The tree layout employs `d3.tree` and `d3.hierarchy` to structure the data, with `d3.linkHorizontal` drawing curved paths between parent and child nodes. Text labels vary in font size based on depth, and users can pan and zoom the entire view via `d3.zoom`. The example loads data from a JSON file and is presented as a static, interactive diagram.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/213cb099ec5a448d8a25f84c889a74f5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
