GNUstep and Directed Graphs

[Chris Beaham]

Hi,

Does anyone have a GNUstep solution/implementation for interactively 
building Direct Graphs, for example analog to the functionality found 
with the XmGraph and XmArc Motif Widgets from Hewlett Packard 
(http://sourceforge.net/projects/xmgraph)?  A GNUstep implementation of 
Graphcet (http://www.lurpa.ens-cachan.fr/grafcet.html) for SFC 
(Sequential Function Chart) generation, or an implementation of AT&T's 
graphviz (http://www.research.att.com/sw/tools/graphviz/) might also be 
nice.  Thanks!

Best regards,

Chris
