{"version":"1.0","type":"rich","title":"ice82","description":"This example presents hierarchical population data as an interactive tree and network visualization. Buttons toggle between a `d3.tree` layout showing parent-child relationships with node sizes scaled by population, and a `d3.forceSimulation` network view with draggable nodes and link lines. The code uses D3 v7 with SVG rendering, drawing colored circles and labels for world regions and countries from embedded sample data.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/747adcd688db41769139546e40446cfe?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
