Is there a better way to point to a sub graph?

Question

I'd like to point to a sub graph where the line stops on the edge. From what I understand I can select any of the nodes in the sub graph. Is there a way to create an invisible node that you can point to?

 digraph G {
    compound=true;
    subgraph cluster_a{ 
        label="node1";
        node1;
    }

    node2->node1 [lhead=cluster_a];
 }

Ideally node1 should not be visible

You may simply use style=invis:

node1 [style=invis];

I have tried that, it does make the node invisible, but it still takes up space. I'ave also tried to set the height and width to 0.0 with the same results. – Marinus Mar 08 '13 at 08:19
Try using `shape=none, label=""` to use less space. Or, if that doesn't work, you may abandon the subgraph's label and display the node's label instead. – marapet Mar 08 '13 at 09:16
