It would be beyond me to place each and every node on TSimpleGraph. I'd like TSimpleGraph to handle this if possoble.,


You should have your graph somehow represented on a file I guess. For each node red from that description you should create nodes and link them programmaticaly. You should read the help file and see what is available. It's not difficult at all!!!

Nop! You should define a policy for node placement. For small graphs or hierarchical graphs it's not difficult, but for large/huge graphs it quite tough.

use InsertNode to create nodes
use LinkNodes to link two nodes
use BoundsRect of node for positioning

read the documentation carefuly - it has all u need.
