{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This visualization displays the hierarchical structure of world countries, organized by continent and subregion. It uses a tidy tree layout where each node represents a geopolitical entity, with edges drawn as curved paths.\n\nBuilt with D3 v5, the code loads hierarchical JSON data and applies a `tree` layout to position nodes. It renders the visualization as an SVG using `linkHorizontal` for connecting paths and includes zoom functionality via the `zoom` event handler. Text labels are styled with the Playfair Display font.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/96bdd3ea25ef4f99ba4b011c9e4f7cf5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
