{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This visualization shows a hierarchical tree of world countries, organized by continent and sub-region. The tree layout displays each country as a text label, with branching paths connecting nations to their regional groupings, using a zoomable interface for navigation. The code uses d3.hierarchy and d3.tree to compute the layout, d3.linkHorizontal for the connecting paths, and d3.zoom for panning and scaling. Data comes from a nested JSON file, and the SVG rendering highlights the structure with teal links and Playfair Display typography.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/e303e17955d543faac3e1e937ec536e0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
