{"version":"1.0","type":"rich","title":"Untitled","description":"This radial cluster diagram displays the hierarchical structure of world regions and countries, using a tree layout where continents branch into subregions and individual nations. The visualization encodes the parent-child relationships through elbow-shaped links, with each leaf node represented by a small circle and a text label. Built with D3.js v3, it loads hierarchical JSON data and applies a cluster layout algorithm to position nodes. The SVG rendering uses the `d3.layout.cluster()` method to calculate coordinates, and custom path-drawing functions to create the connecting lines between hierarchy levels.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/8a90e379cafb497894dea697816aeac0?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
