Version of <a href="//commons.wikimedia.org/wiki/File:CIE1931xy_blank.svg" title="File:CIE1931xy blank.svg">File:CIE1931xy_blank.svg</a> with sRGB primaries and white point. Similar to <a href="//commons.wikimedia.org/wiki/File:CIExy1931_sRGB.svg" title="File:CIExy1931 sRGB.svg">File:CIExy1931_sRGB.svg</a>, but see the description of <a href="//commons.wikimedia.org/wiki/File:CIE1931xy_blank.svg" title="File:CIE1931xy blank.svg">File:CIE1931xy_blank.svg</a> for differences. I used open circles instead of bullseyes to show the colors, but maybe the bullseyes looked better.
