New type of connection lines within a Graph view

Hello! Imagine that you have to make connection between two notes, that will Only explain correlation of one to another. In usual graph view it need to be a separate note in-between of two.
My idea is that it could be an another kind of connection line, that would be a note in itself. (English is not my native language, hope you understand me XD).

Both images contain same Notes (that could be opened and edited), but different in its “type” for a convenient Graph view representation.
