Do you use a specialized LLM for diagrams?

I'm not OP, but I just ask GPT to turn code or process or whatever else into a mermaid diagram. Most of the time I don't even need to few-shot prompt it with examples. Then you dump the resulting text into something like https://mermaid.live/ and voilà.

I just ask chatgpt to generate text diagrams that i can embed in my markdown.
