{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This visualization displays a hierarchical tree of world countries, organized by continent and subregion. The D3.js v5 code uses `d3.tree()` and `d3.hierarchy()` to lay out the data, with `d3.linkHorizontal()` generating the curved connecting paths. Node labels appear as text elements with sizes that decrease with depth, while a `d3.zoom()` handler enables pan and zoom interactions on the SVG. The visualization is based on a static JSON dataset containing the country groupings.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/f30ce74a753a48c1981d062ebb3dffca?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
