{"version":"1.0","type":"rich","title":"Fork of World Countries Trees","description":"This visualization displays the hierarchical structure of world countries, organized by continent and subregion using a tree layout. The data is loaded from a JSON file and rendered as an SVG with horizontal links connecting parent and child nodes. Using D3 v5’s `tree`, `hierarchy`, and `linkHorizontal` functions, the code positions labels with font sizes decreasing by depth and includes zoom functionality via `d3.zoom`. Country names are styled with a Playfair Display serif font, and the visualization fills the entire browser window.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fa958c3807194e709ee386fed9f1f7b8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
