"graphviz" comes with "dotty" and "lneato", which are minimal GUIs for 
creating such ".dot" graphs...

  Depending on your needs for postprocessing or formal constraints on 
the graph you generate, you could use any vector editor (xfig, dia, 
inkscape), assuming you can handle the resulting file format later.

Dedicated graph editors are available

Older:

(other editors such as daVinci or ANGELA! seem to have died..)

Packaging any of these would make a nice addition to SL :-)
