also maybe some creative work needs to be coupled with narratives, if intended for others.

For the example above, one could look at it as a meaningless blob, and someone else could describe it as a run-time behavior with y-axis representing time. Someone else could have some other interpretation. So a narrative could help it fit it in the intended place

Not arbitrarily so. We don't have to throw our hands in the air and declare them infinitely ineffable.
