I dabbled in this area, there are poster layout generation attempts that use gen ai to come up with an initial layout plan, and even feed the visualization back into the llm for iterative fine-tuning.
I was intrigued, but couldn't make it work reliably. Perhaps I forgot to add "make it look nice" to my prompts.

Thanks for sharing. Although diagrams have a unique requirement that the boxes are inter-connected, and those connections must also look "nice".
