English: This is a mathematical diagram, as requested by User:Money is tight on the reference desk question [[:en:Wikipedia:Reference desk/Mathematics#Latex|]] (later [[:en:Wikipedia:Reference desk/Archives/Mathematics/2011 May 13#Latex|]]). See the description of what it depicts there.
The uploaded image itself is only a raster preview. If you actually intend to use this image for real, please use the EPS (encapsulated Postscript) source I will copy here. You can include this EPS version in a LaTeX file compiled by either latex+dvips or pdflatex. This has the font embedded in it. (Make sure to remove the indentation so the dsc comments work.) The image is made by metapost. I also include the metapost source below so that you can modify it.
