For our published documents we've often used graphviz

Here's an example input file.  It mightn't be too difficult to write
an AG save function which generates this format, then use the "dot"
command
to create a postscript image.

digraph timit {
rankdir=LR;
size="7,3";
node [shape=record,width=.2,height=.2,label="",fontsize=18,
fontname="Helvetica"];
edge [fontsize=36, fontname="Helvetica"];

node0[label = "<f0> 0|<f1> 0"];
node1[label = "<f0> 1|<f1> 2360"];
node2[label = "<f0> 2|<f1> 3270"];
node3[label = "<f0> 3|<f1> 5200"];
node4[label = "<f0> 4|<f1> 6160"];
node5[label = "<f0> 5|<f1> 8720"];
node6[label = "<f0> 6|<f1> 9680"];
node7[label = "<f0> 7|<f1> 10173"];
node8[label = "<f0> 8|<f1> 11077"];

"node0":f0 -> "node1":f0 [weight=2,label="P/h#"];
"node1":f0 -> "node2":f0 [weight=2,label="P/sh"];
"node2":f0 -> "node3":f0 [weight=2,label="P/iy"];
"node3":f0 -> "node4":f0 [weight=2,label="P/hv"];
"node4":f0 -> "node5":f0 [weight=2,label="P/ae"];
"node5":f0 -> "node6":f0 [weight=2,label="P/dcl"];
"node6":f0 -> "node7":f0 [weight=2,label="P/y"];
"node7":f0 -> "node8":f0 [weight=2,label="P/axr"];

"node1":f1 -> "node3":f1 [label="W/she"];
"node3":f1 -> "node6":f1 [label="W/had"];
"node6":f1 -> "node8":f1 [label="W/your"];

}
