Graphviz extension cross-referencing

[nicoduchene]

Hi all,

Is it possible to use a sphinx cross-reference (ie. :ref:`ex`) as an href link  in the graphviz dot file?
For example:

digraph example{
FOO [href = :ref:`BAR`, target="_blank"]

}

The desired behaviour is for the FOO node to be clickable and redirect to the BAR section.

Thanks,

Nicolas
