{"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 region, with a root node labeled \"World\" branching down to individual nations. The code uses D3 v5's `tree` layout and `hierarchy` function to compute node positions, then renders horizontal links via `linkHorizontal` and country names as SVG text with font sizes scaled inversely by depth. The visualization reads from a data.json file and supports interactive panning and zooming through D3's `zoom` behavior, with a zoom group applied to the entire SVG canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/14dffdae37fb4c7fb5161cd34536d84c?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
