{"version":"1.0","type":"rich","title":"20_ Tree visualization World countries!","description":"A hierarchical tree visualization displays the hierarchical structure of world countries, organized by continent and subregion. It renders an indented tree layout with curved connecting links, using the D3.js library's `tree`, `hierarchy`, and `linkHorizontal` functions. The SVG output shows country names as text nodes, sized by depth in the hierarchy. The data comes from a JSON file, and the visualization supports zooming and panning through D3's `zoom` event.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/20575aab340942c99a7ed1da6ac0de98?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
