{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This visualization displays a hierarchical tree of world countries, organized by region and subregion, using a horizontal node-link layout. The code renders the structure with SVG paths and text labels, applying D3’s `tree()` layout, `hierarchy()`, `linkHorizontal()`, and `zoom()` for pan and zoom interactions. Data is loaded from a JSON file containing nested country groupings, with label font size decreasing by depth. The visualization uses a custom Playfair Display font and subtle text shadows for readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/17fceeb2e86c44a2b9d9478fe1eb0e12?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
