{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This visualization presents a hierarchical tree of world countries organized by continent and region, using a horizontal dendrogram layout where nodes are labeled with country names. The D3.js code loads JSON data, applies a tree layout to compute node positions, and renders curved link paths and text labels with font sizes that decrease with depth. The SVG output supports pan and zoom interactions via d3.zoom, with styling applied through CSS for stroke colors and font family.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/278d40a56fa343769a7a05946aff7626?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
