A mechanistically generated diagram, i.e. a program reading in something and then emitting a diagram, following a specific algorithm.

> a defined translation from one abstraction layer to another

A solution like the aforementioned cannot reliably present a view with a raised level of abstraction, as that necessitates either making unsound assumptions, or being provided with hints (which can be wrong or expire). Just like with code (because they are code).

And so if this is indeed just a rote visualization like that, sticking to the same level of abstraction (thereby not encountering this issue), then they stipulate it is "almost certainly useless, just like they usually are".

I personally find this agreeable, but then I rarely find diagrams particularly illuminating in general, so...
