{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This example presents a hierarchical tree of world countries, organized by continent and subregion, using a horizontal layout where each node is a country name. The visualization uses D3 v5’s `tree` layout and `linkHorizontal` path generator to draw the branching connections, with labels sized inversely to their depth. The data comes from a local `data.json` file, and the entire SVG rendering supports pan and zoom through D3’s `zoom` behavior, with text styled via the Playfair Display font.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/036643726ed949848d9c59ed5c9214c7?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
