{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This visualization displays a hierarchical tree of world countries, organized by region and subregion, using a horizontal dendrogram layout. The tree structure is rendered with SVG, showing parent-child relationships through curved link paths and text labels that decrease in font size with depth. The code uses D3 v5’s `tree()`, `hierarchy()`, and `linkHorizontal()` to compute and draw the layout, with `d3.zoom()` enabling pan and zoom interactions. Data comes from a local `data.json` file containing nested country groupings.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8cd64cb93c9c44c4b728ea1ddc526451?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
