{"version":"1.0","type":"rich","title":"Dataflow of World Countries Tree","description":"This interactive visualization presents a hierarchical tree of world countries, organized by continent and subregion, using a vertical node-link layout. The D3.js v5 code builds the tree from a JSON file, with country names displayed as text labels. Animated green dashed lines flow along the connecting paths, creating a dynamic data-flow effect against a dark blue background. The visualization employs D3’s cluster layout, hierarchy, and linkHorizontal APIs to position nodes and draw edges, with zooming enabled for exploring the full dataset.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/cff96feb24ae413d86319a889e005689?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
