{"version":"1.0","type":"rich","title":"Projection Transitions w/slider and rotation","description":"This interactive visualization demonstrates smooth transitions between dozens of map projections using two dropdown menus and a slider. Built with D3 v4 and d3-geo-projection, it displays world countries as SVG paths and allows users to morph between any two projections by adjusting a slider, with the transition interpolating projection parameters in real time. The map can also be rotated by clicking and dragging. The visualization includes a graticule overlay and uses a dark land fill with white boundaries, set against a light background. Users select a starting and ending projection from dropdown menus, then use the slider to manually control the morphing animation, with drag-to-rotate adding an interactive 3D feel to the orthographic and other projections.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-082cb12c8f4d5c0d5c4445c16a3db383?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
