State Table Drawing

[abrice2 <abrice2 home com>]

Caution:  Newbie

I'm hoping to write a gtk program to draw a state table from a text file.  
The question I have is how am I going to draw arcs from one state to another 
state and make sure the lines don't cross or overlap?  Not looking for code 
here, just a push in the right direction (widgets and functions to take a 
look at).  Any help would be appreciated.

Thanks,
Aaron
