How to represent FST network visually

[GoogleCodeExporter]

What steps will reproduce the problem?
1. Create parallel Regular expression for two replacement rules
2. like: regex p -> "pl" ,, "p2" -> "p4" ;  

my question is there any tool or library to visualize the compiled regular 
expression as  FST network plotted visually.

Thanks

If you're running Linux or OSX, the "view" command should display the compiled 
FST visually. OSX may require installation of GraphViz 
(http://www.graphviz.org/Download_macos.php). Windows is not supported for 
visualization.

I already installed Graphviz on my Linux RHEL 5.x and after that when i created 
simple foma RE lik regex abc;
then type "view" but nothing happen only the prompt move to new line.
so how can i access the visual fst? is it saved on hard disk as .png file or it 
should display instantly after entr view command?

Finally i found the .png stored under /tmp/ folder also the dot script file
another method i made also:
from foma type: foma[]: print dot > filename.txt
this command will genrate the dot script for drawing the fst

then exit from foma
and type following command from linux terminal:
# dot -Tpng -o outgraph.png filename.txt

thanks
