{"version":"1.0","type":"rich","title":"Projection Transitions v4","description":"This example demonstrates smooth animated transitions between 40 map projections of world landmasses. A dropdown menu allows you to select any of the projections, including Aitoff, Albers, Mollweide, and Winkel Tripel. The visualization continuously cycles through random projections, with each transition interpolating the geographic paths. The map is rendered in SVG with a graticule, sphere outline, and land areas from TopoJSON. D3’s geo-projection plugin provides the projections, and the transition is adapted from Mike Bostock's original block to run perpetually.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-6700d44240d2b6d3ec9767a5a5854e42?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
