[texhax] Simple graph theory diagrams in a document

Colleagues:
Almost exactly a month ago, there were a question about drawing in a
LatTex document. I knew I would need a solution to that kind of
problem, but not just right then. So, I made a note, and left the
problem for the time being. Today, I looked at what I assumed was the
outcome of the recomendations: pgf/tikz.
Dear me, a 248-page manual in color. A very powerful tool.
Obviously. And very obviously a blatant overkill in my case.
I am writing a text within psychology there I employ basic stuff in
graph theory. The primary tool is what is called "signed and directed
graphs", consisting of a set of points ("dots" on the paper) and a set
of relations between them in the form of arrows (dashed for negative
and solid for positive, which may be curved if there are arrows in
both directions between two points).
So I need to draw something like that in the MS, only consisting of
very few points, maximum of say five. Possibly with some kind of
label (x1, x2 etc.) on the points, and possibly with some value (-2 to
+2) associated with the relations or arrows.
In other words, what I need is something that is "good enough", less
of an overkill, but still producing nice diagrams.
Any suggestions?
Tom
