{"version":"1.0","type":"rich","title":"World Countries Tree","description":"This hierarchical tree visualization displays the geographic organization of world countries, branching from continents down to sub-regions and individual nations. The data, loaded from a JSON file, is structured in a nested parent-child format. Using D3 v5 APIs, the code applies a `tree` layout and `hierarchy` function to process the data, then connects nodes with horizontal links and displays text labels. The visualization is rendered as an SVG, using the `linkHorizontal` generator to draw the tree paths.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/33d5f0d281054c0b986f50bec84b86ff?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
