rank expression

[etajima]

I would like to express "{rank=same; node1 node2}", but could not find any sample.
Is it possible to do this with node-graphviz?

Thank you.

I was wondering the same.

@etajima it appears to be unsupported. The usage 'S' is unique and not included in the supported attributes as far as I can see:

rank: { usage: 'S', type: 'rankType' },
