Add image or text to border of rectangle or cluster - graphviz

I have a code that allows me to perform a cluster. i want to move the label to the border of the cluster in the output. I have tried labelloc=l and other options but i am unable to make it work. attached is the one i got from graphviz while the other one is what i was expecting. is there a way to modify the code, add plugin or gvpr to get the desired output?

This is an example of an Alignment Map visualized with the help of Graphviz.
This solution depends on either generation or maintaining a .dot file and from that generating a image or document.
Personally, I think that editing the file by hand should be fine if the naming conventions used are intuitive.
Alignment maps first came to my attention on Martin Fowlers blog (http://martinfowler.com/bliki/AlignmentMap.html).

} The one on right is graphviz and left is what i expect

Solution

  • (sorry, I misunderstood the request)
    Here is a gvpr "fix".

    1. run dot -Tdot to position the nodes, edges, clusters
    2. run that result through gvpr (program below) to remove the label and replace it with a (new) node
    3. run that (modified) result through neato -n2 -Tsvg (see https://graphviz.org/faq/#FaqDottyWithCoords)

    [note that I had to tweak the html to remove borders:]

     label=< <table BGCOLOR="transparent" BORDER="0" CELLBORDER="0" CELLSPACING="0">
       <tr><td fixedsize="true" width="50" height="50"><img src="image_dir/Face-smile.svg" /></td></tr>
       <tr><td>Active Directory</td></tr>
   </table>
>

    commandline:

    dot -Tdot myfile.gv|gvpr -c -f moveLabel.gvpr | neato -n2 -Tsvg >myfile.svg

    moveLable.gvpr:

    BEGIN{
  string saveLbl, saveX, saveY, workS;
  graph_t theG;
  node_t newNode;
}
BEG_G{
  print("// ONE");
  theG=subg($G, "cluster_IT_outcome");
  saveLbl=theG.label;
  // next 3 steps get the left X coordinate of the cluster
  workS=llOf(theG.bb);
  workS=xOf(workS);
  saveX=(float)workS;
  // now get Y coordinate of label
  workS=yOf(theG.lp);
  saveY=(float)workS;
  theG.label="";     // remove label from cluster
}
END_G{  
  // create new node to replace cluster label
  newNode=node($G, "__myNewNode");
  newNode.pos=sprintf("%.2f,%.2f", saveX, saveY);
  newNode.shape="plain";
  newNode.fillcolor="none";
  newNode.label=html($G, saveLbl);
}
