{"version":"1.0","type":"rich","title":"World Countries tree","description":"This visualization displays the hierarchical structure of world countries, organized by continent and region, as a horizontal tree diagram. D3’s `tree` layout computes node positions, while `linkHorizontal` generates the curved connecting paths. Labels show country names with font sizes decreasing by depth, and a `zoom` behavior enables pan and zoom interactions. The diagram uses an SVG renderer and loads hierarchical JSON data containing continent, region, and country groupings.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/ff32c629a4c1462aaadc4543d114bc4f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
