{"version":"1.0","type":"rich","title":"Yohoo","description":"A hierarchical treemap visualizes the nested structure of world regions, from continents down to individual countries. The visualization uses a tidy tree layout to arrange nodes in a radial pattern, with each node represented as a circle and connected by curved links. The code employs `d3.hierarchy` and `d3.cluster` to compute the layout, rendering the result as SVG elements. Node labels show the region or country names, while the root node is highlighted with a different color. The example loads data from a `data.json` file containing the geographic hierarchy and uses `d3.select` to manage the SVG canvas.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/28c0c5c60ab84fffb3495de1cb4db210?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
