{"version":"1.0","type":"rich","title":"World Countries Tree","description":"A circular tree layout displays population data for ten major countries, with each country as a leaf node sized by its population value. The visualization uses a fixed-size SVG canvas with a rounded background rectangle. The code builds the hierarchical layout using D3's tree module and renders the nodes and links as SVG elements. The data comes from a static CSV file read through D3's data-loading methods, and the visualization updates through D3's standard enter-update-exit pattern.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/33ef940bf2d5421e9849d4e504a23eea?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
