[pstricks] Drawing graphs

[Paulo J. Matos]

Hi all,

Is there any higher-level environment in pstricks for drawing graphs
like \pstree, or not? I have Latex Graphics Companion but defining
graphs like the ones they have here requires me to define a position
for each node which is not nice. Is there any other way?

Cheers,
