I was trying to draw a geometric graphs using latex, unfortunately, latex
is very limited for drawing graphs. So, I used pictex. Unfortunately,
I always get the "out of memory" error. In the end I resort to using
postscript to draw my graphs.

My postscript routine is given below

--------------------------------------------------------------------

/aline {

I have several questions ...

1. How can I include this postscript file in my Latex file as a figure?
2. Is there any written macro for drawing graphs (nodes and edges)?
3. How can I graph a straight length between any 2 points in TeX?



Thanks.
