{"version":"1.0","type":"rich","title":"Link Tree Viz of World Countries","description":"This visualization displays a hierarchical tree of world countries as an interactive node-link diagram. The view uses blue circles for nodes and curved, arrow-headed paths for directed links, with all elements offset vertically by 150 pixels. The implementation relies on D3 v5's `linkHorizontal` generator to create smooth horizontal curves between connected nodes, while data is loaded from a local JSON file via `d3.json`. The SVG rendering positions nodes based on explicit x,y coordinates from the data, and the visualization includes marker definitions for the arrow tips.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/6a7566b06f6545c1b4b1b312a4ff78cb?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
