{"version":"1.0","type":"rich","title":"Mind Map","description":"A hierarchical mind map displays the geographic structure of the world, starting with continents like Asia and drilling down through sub-regions to individual countries. The layout uses a horizontal tree, where each node’s depth determines its font size, and the connecting links are drawn as smooth horizontal curves. Built with D3 v5, the visualization leverages `d3.hierarchy`, `d3.tree`, and `d3.linkHorizontal`, and includes a zoom interaction via `d3.zoom`. Text labels are rendered with SVG elements, and the styling uses the Playfair Display font.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/c8dbe5a0dd77486193a9a8808f45f5af?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
