{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This visualization presents the hierarchical structure of world countries, organized by continent and subregion, as a radial-style tree diagram. It renders the data as a horizontally oriented tree using SVG paths and text labels, with node positions computed by the `tree()` layout and `hierarchy()` functions from D3 v5. The visualization supports pan and zoom interactions through the `zoom()` behavior. Text labels display country names with font size decreasing by depth, and the data is loaded from a local JSON file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/b9f2a6fcf58c476b85b56e127f5956c2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
