{"version":"1.0","type":"rich","title":"World Population Tree","description":"This interactive visualization shows the hierarchical structure of world population data, organizing countries into regions and subregions like Southern Asia and Western Asia. It presents a tree layout where the root node represents the World, branches into continental groupings, and extends to individual countries. The visualization uses D3.js version 5, employing the `tree`, `hierarchy`, and `linkHorizontal` APIs to compute the layout and draw curving links between parent and child nodes. The font size scales with depth, making higher-level categories appear larger, while pan and zoom functionality is enabled through the `zoom` event handler.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/2ad1865c684c473eb8b613afb53c9b9e?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
