To add to the list of possibilities, I use the drawing side of open
office for this kind of thing, export as a pdf, and use pdfcrop to crop
the figure (i.e., remove the full page of white space). Exporting as eps
or bitmap also works. Openoffice draw has connectors and nodes of
various styles (straight, curved, ...).

For more involved diagrams I use scribus, which is more of a dtp
programme but with a lot of drawing capabilities, as it generates really
nice pdf (and ps) exports.

Both are open source and multi-platform.
