Graph editors are useful when the nodes represent meaningful abstractions over the underlying code for whatever the domain is. For example, I could use a bunch of arithmetic nodes to implement matrix multiplication, but a RotateAroundPoint node would be far more useful and desirable. For low-code users, this is often exactly what they need. You could write a RotateAroundPoint function for them to use, but then they’re still managing a lot of the boilerplate around writing code. Graph editors solve many of these pain points when the correct nodes for the problem-space are offered.
