Hello, many thanks for this library!

I have a question which is duplicate of this issue here:

#9 (comment)

In a manual graphviz chart I have the following setup.

At the top of my graph I have defined:

  newrank=true;

As part of my graph I have the following anonymous graph:

{ rank=same; some_node_1; some_node_2; }  # How to inject this line?

This works, however similar to the issue linked above, how do I accomplish this in gographviz?
