{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This visualization displays the hierarchical structure of world countries, organized by continent and subregion, as an interactive tree diagram. The D3.js visualization (v5) uses the `tree` layout algorithm with `linkHorizontal` edges to render the hierarchy as an SVG, with node labels sized inversely to their depth in the tree. The code loads country data from a JSON file, applies a `hierarchy` transformation, and supports zooming and panning via the `zoom` event, which adjusts the transform of the SVG group containing the tree.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b8cf1eb2652040b8af06a75bcb57dcfc?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
