{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This visualization displays the hierarchical structure of world countries, organized by continent and subregion, as an interactive tree diagram. It uses D3 v5’s `tree` layout, `linkHorizontal` generator, and `zoom` behavior on an SVG canvas, with nodes labeled by country names. The data is loaded from a JSON file, and the static layout supports pan and zoom via D3’s zoom event. Text size decreases with node depth to emphasize hierarchy.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/076c0691a39d4c39984485081d996344?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
