{"version":"1.0","type":"rich","title":"Tree Visualization of World Countries.js","description":"A hierarchical tree visualization displays countries grouped by continent and subregion, with the world as the root and individual nations as leaf nodes. The layout uses D3's `tree` and `hierarchy` functions to position nodes, while `linkHorizontal` generates curved paths connecting them. The SVG rendering applies zoom functionality from D3's `zoom` event, and text labels scale in font size based on node depth. Styled with a Playfair Display font and text shadows, the visualization reads hierarchical country data from a local JSON file.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/a7fecdb301e54eb4a5e5b912d60073a2?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
