A bit off topic, but I am curious about your experience with Structurizer. My experience wasn't so positive (albeit the general incentive that it's open-source and local).

It's pretty ungainly for anything more than toy models. The rendering's rather hideous too.

If you just want pretty C4 models, Draw.io is your best bet. But then you lose all the fun linkage between your code and models.
