{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This visualization shows a hierarchical tree of world countries, organized by continent and subregion, with each country name displayed as a text label. The tree layout positions nodes horizontally, with links drawn as curved paths in green. The visualization uses D3 v5's `tree` and `hierarchy` functions to compute the layout, `linkHorizontal` for path generation, and `zoom` for pan and zoom interactions. Data is loaded from a JSON file, rendered as SVG, and styled with the Playfair Display font.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c6f9497ab9c840a7a39f2a7f5c2abc4f?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
