{"version":"1.0","type":"rich","title":"Art tree!","description":"This visualization renders a hierarchical tree of world regions and countries from a JSON dataset, with the root labeled “World” branching into continents and subregions. It presents the data as a horizontal tree layout, where each node represents a geographic entity. The code uses D3 v5’s `tree` and `hierarchy` functions to compute the layout, and `linkHorizontal` to generate curved SVG paths for the connecting links. The tree is sized to fill the browser window, and the SVG is updated dynamically.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/88316cd6da0c48bf9fd3ba349cea97a9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
