I am sorry for what I imagine is an annoyingly trivial question -- I am technologically challenged. I was trying to learn a bit of postscript (to draw some fun fractals) but unfortunately, I am stuck already at the hello world stage. Namely, I have the following simple file called file.ps:
%!PS
newpath
72 72 moveto
200 200 lineto
stroke
showpage
Running gs appears to go well but no graphical window opens up.
$ gs file.ps

Somehow, I'm not finding anything useful online with regards to this issue, so I thought I would try asking here. Any thoughts on how I can get a window to display with gs? If it is relevant, I am doing all of this on my mac.
