Subgraph cmdlet and the invisible node (A Harry Potter Movie) #111

Open rebelinux opened 10 months ago

rebelinux commented 10 months ago

Hi,

Evaluating the generated .dot file I noticed that for each SubGraph a node with the same name as the subgraph is created.

I have seen that in some cases this invisible node messes up or influences the calculation of the edges.

Is there any reason for this?

PSGraph code: https://github.com/KevinMarquette/PSGraph/blob/054765334c12ef9a6549380ae2661fda26c11255/PSGraph/Public/Graph.ps1#L118C1-L123C14
