{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This fork of the World Countries Tree shows the hierarchical structure of global regions and their member states from CSV data. The treemap-style layout uses a horizontal dendrogram that arranges continents, subregions, and countries as nodes, with leaf labels gradually decreasing in font size by depth. The visualization relies on D3 v5's `tree`, `hierarchy`, `linkHorizontal`, and `stratify` APIs to compute the layout and draw SVG paths and text. Interaction is limited to zooming via the `zoom` event handler.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2bfd334146ff4413aed5873e3e6427e4?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
