{"version":"1.0","type":"rich","title":"World countries Tree","description":"This visualization presents a hierarchical tree of world countries, organized by continent and subregion, with the country names displayed as text nodes. The layout uses a horizontal tree structure where the depth of each node is reflected by its font size in the SVG rendering. The visualization leverages D3 v5's `hierarchy`, `tree`, `linkHorizontal`, and `zoom` modules to position and connect the nodes, reading the data from a local `data.json` file. It renders as an interactive SVG that supports zooming and panning.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6b6cb97dea9b4a4d921361dbd039c621?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
