{"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 collapsible-free horizontal layout. The code builds the tree with `d3.tree` and `d3.hierarchy`, rendering links as horizontal paths via `d3.linkHorizontal`. Text labels scale in font size based on depth, and the entire view supports pan and zoom through `d3.zoom`. Data comes from a pre-structured `data.json` file, and the SVG is styled with custom CSS using the Playfair Display font.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f7dd8535f3b8408ba470236e924cdc27?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
