{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This example shows a hierarchical tree of world countries organized by continent and subregion, with nodes labeled by country name and connected by curved links. The visualization uses the D3 v5 `tree` layout and `hierarchy` to structure the JSON data, while `linkHorizontal` generates the paths between parent and child nodes. Panning and zooming are enabled through the D3 `zoom` behavior. Labels scale in font size based on their depth in the hierarchy, and the entire graphic is rendered as SVG with a fixed, full-screen viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/62933622c90849b1ae629a0143fadd57?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
