{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This visualization shows the hierarchical structure of world countries organized by continent and subregion, with each country name displayed as a text label connected by branching paths. The tree layout uses `d3.tree` and `d3.hierarchy` to compute node positions, while `d3.linkHorizontal` draws the curved links. The SVG rendering supports pan and zoom via `d3.zoom`, and text styling uses a Playfair Display font with white shadows for readability. Data comes from a JSON file containing the nested geographic hierarchy.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/63e62c8b85b145b49c033a26efe6dfae?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
