{"version":"1.0","type":"rich","title":"Tree with Countries","description":"This visualization shows the hierarchical structure of countries organized by continent and subregion, with each country’s name displayed as a leaf node. The tree layout, generated using `d3.tree` and `d3.hierarchy`, positions nodes horizontally, and links are drawn with `d3.linkHorizontal` as SVG paths. Labels scale in font size based on tree depth, from large continent names to smaller country names, while the entire diagram supports pan and zoom via `d3.zoom`. Data is loaded from a JSON file using `d3.json`, and the SVG output is styled with a tan path color and a custom font.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8debc25cf5a84134b0ddcb21c4046aa3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
