{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This tree visualization displays the hierarchical structure of world countries, organized by continent and subregion down to individual nations. Using D3.js v5 with the `tree` and `hierarchy` layouts, it renders an SVG with horizontal links via `linkHorizontal` and text labels sized by depth. The visualization supports pan and zoom through the `zoom` API, with data loaded from a local JSON file. Text styling uses the Playfair Display font with white shadows for readability against the mint-colored paths.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9c84563963504b9fab72d283139c16f0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
