To my knowledge there is no way to make the results from a dataview snippet/result to populate the graph view. This means your results from a dataview query indeed can create links to various files depending on your query, but that result will not show up the graph view.
I am guessing this is because the graph view literally reads your static files and populates based on links, tags etc that are all hard-coded in to those static files.
Dataview on the other hand does its calculations every time a particular file is loaded and that particular query is loaded, but also only then. The result isn’t “stored” somewhere.
If dataview were to be able to populate the graph each of the dataview queries would need to be run in ALL your files every time you opened a new file (to check if something, somewhere had changed). In large vaults this would be a massive calculation.
The only theoretical way around that would be if there somehow, somewhere, was a query caching function that made the query results semi-permanent so they could be read by the graph functionality. This, to my knowledge, does not exist.
