{"version":"1.0","type":"rich","title":"Fork of World Countries Tree","description":"This interactive visualization presents a hierarchical tree of world countries, organized by continent and subregion. The layout displays each entity as a text label connected by curved paths, with font size decreasing based on depth in the hierarchy. The visualization uses D3.js v5 to load the JSON data, and applies the `tree` layout algorithm with a horizontal link generator. Users can pan and zoom the entire structure through the `zoom` event handler, which transforms the contained group element. The data comes from `data.json`, and the styling uses the Playfair Display font with white text shadows for readability.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/0f756a66b0c4420f9529844b75744412?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
