{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This visualization presents the World Countries Tree, a hierarchical diagram that organizes every country into its corresponding continent and subregion. The tree uses a vertical layout, with the root node \"World\" branching into continents like Asia and further into regional groupings and individual countries. Built with D3.js v5, the example employs the `tree` and `hierarchy` layout functions, rendering links as SVG paths and labeling nodes with text elements. Pan and zoom interactions are supported via the `zoom` behavior, and the data is loaded from a local `data.json` file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b26c1f7e9ef744d38a48c727d0e2b237?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
