{"version":"1.0","type":"rich","title":"Azimuthal Equidistant Raster Reprojection","description":"This example demonstrates an azimuthal equidistant raster reprojection, converting a cylindrical equirectangular Blue Marble image into a disc-shaped Earth view using d3.geoAzimuthalEquidistant. It draws the original JPEG to a Canvas, then uses projection.invert and getImageData to sample source pixels for each target pixel, while calculating the projection disc’s radius to blank out areas outside it. The result is a direct pixel-level transformation rendered entirely on canvas.","provider_name":"VizHub AI Studio","provider_url":"https://next.vizhub.com","html":"<iframe src=\"https://next.vizhub.com/viz/gist-56cbf086b64406aaf81b630426bad5e9?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"1\"></iframe>","width":960,"height":500,"cache_age":3600}
