{"version":"1.0","type":"rich","title":"Art Tree","description":"This visualization displays a hierarchical tree of world regions and countries from a JSON dataset, with each node labeled by its geographic name. The tree layout uses D3 v5’s `tree()` and `hierarchy()` functions, while horizontal curved links are generated with `linkHorizontal()`. Text size decreases with node depth, and the SVG rendering supports pan and zoom via D3’s `zoom()` behavior. Labels include white text shadows for readability, and the layout fills the full browser viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f53eda177fe34683b3dff6e8859dffe6?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
