{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This visualization shows the hierarchical organization of world countries, categorized by continent and subregion, as an interactive tree diagram. The layout uses D3’s `tree` and `hierarchy` functions to position nodes, with `linkHorizontal` generating curved paths for parent-child connections. Text labels scale in size by depth, and a `zoom` behavior allows panning and scaling the entire SVG view. Data comes from a local JSON file, rendered with SVG elements styled using a green stroke and a serif font.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/95a9ca4677934ad3a2b7ca39937cdc56?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
