I was also very interested in finding a TF auto-diagramming tool at some point. After researching some examples however, I became convinced that it's not something I actually wanted or could make proper use of.

The issue I had with them is that they were just plain confusing and "noisy". After reflecting on it a bit, this made sense. Diagrams are only ever easy to follow if they have a clear purpose, but with minimal to no human semantic context, these auto generated diagrams could never be that way. They were just aimless scattershots of boxes with pretty icons on them.

Maybe it was just me not being used to them enough, and I could have grown to appreciate them and utilize them well if I bothered for long enough. But if I think about what I'd want from a diagram, it would be things like how data flows through an infrastructure, which Terraform cannot hope to have an exact idea about. And this only gets worse when you upload custom code, such as by using lambdas, containers, ec2 instances, what have you.
