{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This visualization displays a hierarchical tree of world countries organized by continent and subregion, using a left-to-right layout with horizontal links. Built with D3 v5, it leverages `d3.hierarchy` and `d3.tree` to process the JSON data, while `d3.linkHorizontal` generates the curved paths. The SVG renders country names as text nodes with font size decreasing by depth, and implements `d3.zoom` for panning and scaling. Data comes from a static `data.json` file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f7b4955bd66546f593a26085ab6f48d0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
