{"version":"1.0","type":"rich","title":"Art Tree","description":"This visualization shows a hierarchical tree of world regions and countries, with the global structure flowing from a root \"World\" node through continents and subregions down to individual nations. The tree layout uses a horizontal orientation, where parent-child connections curve gently between levels, creating a branching structure that resembles an abstract botanical form. The code imports `select`, `json`, `tree`, `hierarchy`, and `linkHorizontal` from D3 v6, then applies the `tree()` layout to position nodes and generates curved link paths using `linkHorizontal()` with swapped x and y coordinates. Data comes from a static JSON file containing the geographic hierarchy, rendered as SVG paths that fill the entire browser viewport.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/303fa969e3e441bb9fe027d19518d848?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
