I agree that mind maps aren’t a universal solution — they can add cognitive load if the structure doesn’t match how someone thinks. I’m not assuming visuals are “better,” only that for some people, seeing relationships helps reduce the wall-of-text problem.
The question is more about understanding limits as much as benefits. If you’ve found approaches that work better for you, even at a high level, I’d still be interested — not to commercialize them, but to understand where visualization breaks down.
