{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This visualization displays the hierarchical structure of world countries, organizing them by continent and subregion into a horizontal tree layout. The root node, \"World,\" branches into continents like Asia, which further divide into subregions and individual countries. The SVG rendering uses D3.js v5’s `d3.tree`, `d3.hierarchy`, `d3.linkHorizontal`, and a zoom interaction via `d3.zoom` to navigate the large dataset. Node labels are positioned with dynamic font sizes based on depth, and the data loads asynchronously from a JSON file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/d60853364c674fbcb79826bf496381a5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
