{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"A world map is visualized as a hierarchical tree, with continents, sub-regions, and individual countries as nodes. The tree layout is computed using D3’s `tree` and `hierarchy` functions, and links are drawn with `linkHorizontal`. Node labels are positioned with scaled font sizes based on depth, and the SVG output is styled with a green link color and a serif font. The visualization supports pan and zoom via D3’s `zoom` event, with the data sourced from a JSON file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0c075fbc96db41008b79843de62a4a76?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
