{"version":"1.0","type":"rich","title":"Fork of Fork of World Countries Tree","description":"This visualization presents a hierarchical tree of world countries, organized by continent and subregion, using a horizontal dendrogram layout. The code employs `d3.tree()` and `d3.hierarchy()` to compute node positions from a JSON data file, with `d3.linkHorizontal()` generating smooth curved links between parent and child nodes. Interactive zooming is enabled through `d3.zoom()`, allowing users to explore the full dataset. Node labels are rendered as SVG text elements with font sizes that decrease per depth level, while paths are styled with a teal stroke and Playfair Display typography.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/3b8ca0cbb2944d44af828c6595454fd8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
