What packages do you use and recommend for creating graphics in your LaTeX documents?
As this is a community wiki post, please add your package to the accepted answer (or add a comment, and someone with >100 rep will add it to the CW answer), and include a brief description of what differentiates it from others and how it can be used (GUI drawing tool which generates code, type in raw text, or generates image for inclusion in document). We'll eventually sort these answers under headings.

I've compiled this list. I don't have experience with most of these, but, if you do, please add more descriptive text to your package. If it does not appear, again, please add it. If you don't have the rep to edit, post it in a comment and @ messgage myself or the last editor. Also, if you feel that a certain element should not be in the list, remove it and leave a note in your edit explaining why it was removed.
The big ones:
#1 PGF/TikZ. The standard. As Dima said, it's "powerful, flexible, easy to use, and stunning". TikZ provides a high-level user interface. PGF provides lower-level macros.
#2 PStricks. Probably the second most used package.
#3 The default packages. More used than the others, but not by reason of being more powerful. These are mostly useful for including external images (e.g.
graphicx
) or combined with other packages (e.g.xcolor
is used by PGF/TikZ).Other graphics packages and programmes typically included in TeX distributions include:
Independent GUI wrappers and tools which create images suitable for inclusion in LaTeX documents include:
