{"version":"1.0","type":"rich","title":"Reprojected Raster Tiles","description":"This example demonstrates dynamic reprojection of raster map tiles in D3, allowing the user to interactively explore the globe using an azimuthal equal-area projection. Built with Canvas rendering, it fetches standard web map tiles from Stamen and reprojects them on the fly using a custom quadtree-based tile-splitting algorithm (d3.quadtiles.js). The map supports zoom and pan, and the projection can be switched among several options (conic conformal, Robinson, Mercator) to show how raster tiles adapt to different coordinate systems. The author notes that non-original projections may cause visual artifacts, such as compression near the equator, highlighting the technical challenges of raster reprojection.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-ed65408dda92941397cc63658a4da20a?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
