Stupid Dot tricks

Show and Tell
1

Experimenting with stylized diagrams, I created a gvpr program that would post process an enhanced dot program, adding row, column, and cellAdjust (the last tweaks the position within the cell).
I use dot to establish all the standard attributes, then my gvpr program to reposition all the nodes, based on the new attributes, then neato -n to route edges and produce the output.

Thanks for the contribution @steveroush and welcome to the forum :smiley:.

I haven’t used gvpr myself. What does the gvpr program that creates this look like?

That program is a work-in-progress (currently broken) (feature creep).
If you are interested in gvpr programs in general, you can find them here (maybe) in a Linux install: /usr/share/graphviz/gvpr/ or here if you built your own from git: …/cmd/gvpr/lib/
Here is a little program that counts nodes, edges and the number of characters in the node and edge labels:

BEGIN {
  int nodeCnt=0, edgeCnt=0, nodeLabelCharCnt=0, edgeLabelCharCnt=0;
}
N {
  nodeCnt++;
  nodeLabelCharCnt+=length($.label);
}
E {
  edgeCnt++;
  edgeLabelCharCnt+=length($.label);
}
//////////////////////////////////////////////////////////
END_G{
   print ("Total nodes: ", nodeCnt);
   print ("Total edges: ", edgeCnt);
   print ("Total node label character count: ", nodeLabelCharCnt);
   print ("Total edge label character count: ", edgeLabelCharCnt);
}
