{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This visualization displays the hierarchical structure of world countries, organized by continent and subregion. It uses a tree layout with horizontal links connecting parent and child nodes, rendered as SVG paths and text labels. The code employs D3 v5’s `tree`, `hierarchy`, and `linkHorizontal` functions to compute positions and generate curved paths, with `zoom` enabling interactive panning. Country names appear with font sizes scaled by depth from `data.json`, which groups nations under regions like Southern and Western Asia, making the geographic taxonomy easily explorable.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/940654e554d54eda8d74ce23ba3baa65?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
