{"version":"1.0","type":"rich","title":"world countries tree","description":"This visualization presents a hierarchical tree of world countries, regions, and subregions as an SVG graphic. It uses a D3.js tree layout to position the data in a radial or icicle-like structure, with horizontal links connecting parent and child nodes. The code imports functions like `tree`, `hierarchy`, and `linkHorizontal` from D3 v5, loads the hierarchical data from a local `world.json` file, and renders the connections as SVG `path` elements.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/65501db7ae1d45f1a5538c4283a0928e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
