Hello everyone,
I am somehow new to Graphviz, used it for a little while, but don't know some advanced features.
Here is what I want: I want to create a subgraph without creating an additional node. Now if I have a subgraph, the subgraph will be displayed next to the main graph, and a symbolic node representing the subgraph will be added to the main graph. I now want that in the main graph the subgraph links directly into main one. Of course in this case the outline of the subgraph will be drawn, and the edge to the subgraph will link to the outline.
