{"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 horizontal tree layout rendered as SVG. The code uses D3 v5's `tree` layout and `linkHorizontal` path generator to position nodes and draw connecting links, with country names displayed as text labels sized by depth. Data comes from a JSON file containing a nested structure of world regions and countries, while zooming is implemented via D3's `zoom` behavior.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/92cb1293548d49aeba16f0b4e5be9c00?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
