{"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 sub-region, as a horizontal tree diagram. The SVG rendering uses the D3.js library’s `tree` layout, `hierarchy`, and `linkHorizontal` components to position nodes and draw connecting paths. Country names appear as text labels, with font size decreasing at deeper levels, and an interactive `zoom` feature allows users to pan and scale the view. Data is loaded from a local `data.json` file, and the styling is applied via CSS, including a Playfair Display serif font.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/24d2cbef43b1484483f7d23d3d8d1f5b?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
