Separate unlinked clusters in graph view

In the graph view, separating out clusters that do not have any links among them would make the visualization much clearer.

As an example, I’ve created two links:
File 1 --> File 2
File 3 --> File 4

And the graph view shows:

So unless I look closely, this appears like all four are interrelated files.
Having them be separate clusters would be much better.
