{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This visualization shows a hierarchical tree of world countries organized by continent and region, with each country displayed as a text label and connected by curved links. The D3 v5 code loads a JSON dataset and uses `d3.tree` and `d3.hierarchy` to compute the layout, while `d3.linkHorizontal` generates the curved paths. Text size decreases with depth, and a `d3.zoom` behavior enables panning and zooming on the SVG.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c1593581948c4a46a5e7662dc29d8657?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
