{"version":"1.0","type":"rich","title":"Tree Visualization","description":"This interactive tree visualization displays the hierarchical structure of world regions and countries, using a horizontal dendrogram layout. The visualization reads from a JSON data file and renders an SVG using D3 v5, with nodes labeled as text and links drawn as paths. It includes zoom and pan functionality through D3’s `zoom` event, while the layout is computed with the `hierarchy` and `tree` APIs. Text elements are styled with a serif font and white text-shadow for readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d69e7ce3a50b4d5898a88ab74942ec27?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
