{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This visualization presents the hierarchical structure of world countries organized by continent and subregion, rendered as a horizontal tree layout. The geographic data is loaded from a local JSON file and displayed using SVG elements. Built with D3 v5, the code applies `tree()` layout, `linkHorizontal()` for curved edges, and `zoom()` for panning and scaling. Text labels use a Playfair Display font, with font size decreasing by depth level to emphasize hierarchy.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/fda08d620de94a488c4aaeaf36d0d4d3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
