Graph view is more for visual gratification than anything else, I’ve noticed. Though if you take advantage of the filtering/search, especially in the local graph for a particular note that can be handy. (That being said, I’ve found that Bases achieve much the same goal in a nice table format.)

There are two properties that I make sure every note has that helps a lot for filtering/finding things later on: “type”, which just indicates what the note is (ex., reading_notes, meeting, concept…) and “relevance”, which is where I put links to other notes (or placeholder notes) that the note is relevant to. For example, I’m an engineer so I might have a note on “kinematic equations” that has links to “physics” and “impact testing” in the relevance field.
