I am currently strugelling with the following problem:
I would like to create a TikZ graph in which I can click on the node text (hyperref) to jump and zoom in to another part of the graph:

I thought about
\begingroup
\hypersetup{pdfview={XYZ ?? ?? ??}}
\hyperlink{hello}{Reference}
\endgroup
what kicks in the problem of knowing the exact PDF coordinats and zoom factor for the node. (Can TikZ provide that?)
Do you know any solution for that?
