{"version":"1.0","type":"rich","title":"Tree","description":"This visualization shows a hierarchical tree of world regions and countries, with the root labeled \"World\" branching into continents like Asia and sub-regions such as Southern Asia, and further into individual nation names. It uses D3 v5’s `tree` layout to compute node positions and `linkHorizontal` to generate curved SVG paths for the connections. The code loads hierarchical data from a `data.json` file and renders links in an SVG element sized to the browser viewport, without displaying node labels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f3aab16b77594af998cae2bdc828b3d8?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
