{"version":"1.0","type":"rich","title":"Fork of Fork of World Countries Tree","description":"This visualization presents a hierarchical tree of world countries, organized by continent and subregion, using a branching layout that expands from left to right. The data is loaded from a JSON file, and the tree structure is rendered as SVG paths and text labels. The code uses D3 v5’s `tree()` layout, `hierarchy()`, and `linkHorizontal()` to compute the layout and draw the connecting links. Users can pan and zoom the entire diagram via the `zoom()` behavior, with text sizing decreasing at deeper levels to fit the hierarchy.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f214e4c5daae4d98aee13dbd3e010dfb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
