{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This visualization displays the hierarchical structure of world countries organized by continent and subregion using a tree layout. It reads a nested JSON data file and renders the hierarchy as horizontal links with country names positioned along the branches using SVG elements. The implementation uses D3 v5's `tree()` and `hierarchy()` functions, with `linkHorizontal()` for path generation and `zoom()` for panning and scaling. Text styling employs Playfair Display with white shadows for readability against the teal link strokes.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/138ae01d321b487eaa723d684504e13c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
