{"version":"1.0","type":"rich","title":"Fork of World Countries Tree1","description":"This visualization presents a radial tree layout of world countries, hierarchically organized by continent and subregion, with each country displayed as a text label. The tree expands from a central \"World\" root node, with connecting curved links rendered as green paths. Using D3 v5, the code employs `d3.tree()`, `d3.hierarchy()`, and `d3.linkHorizontal()` to compute and draw the layout. Labels are sized inversely to their depth in the hierarchy, with deeper nodes rendered smaller. Data comes from a local `data.json` file, and the SVG output is styled using the Playfair Display font.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/9799010bc57f46ce9df6703dc61971e5?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
