Sometimes I draw UML-like diagrams when I join a project (and when the project is big enough in such a way my mind melts if I try to keep track of everything), I wonder if there are equivalent representations of such things.

Linear text is perfect to me for documentation, teaching/learning etc...

But also, systems seems to be better digested under the shape of spatial representations (I met a lot of CS persons that fantasized over the possibility of displaying all the files of your codebase in a VR-like environment augmented with visual cues (UML) and I must admit that I would find this unnecessary but comfortable -- and I can imagine applications of this in other domains; imagine a teacher arranging the whole of Kant philosophy as a spatial-visual system referencing positions, comments, etc..). Eyes are cool because you can focus on something while knowing that some available information is there around the zone you are focusing; in a sense, so is the hand, locally, but I imagine (I dont know) it would require some super-human level of braille reading to be able to jump back and forth reading on different fingers, so that's again a probably stupid question to ask to the blind crowd of hn : are you able to do this?
