{"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, with each country positioned as a leaf node. The layout uses a horizontal tree structure rendered as SVG paths with red links connecting parent and child nodes. The implementation loads country population data from a CSV file and hierarchical structure from JSON, then applies `d3.tree()` and `d3.hierarchy()` to compute node positions, while `d3.linkHorizontal()` generates the curved connecting paths.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/4342bbe5c68946d0834def667406738f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
