> Not my experience at all - if anything I'd say visual aspects tend to be a marker of less rigorous communcation.
I would point to the field of combinatorics, the traditional proofs of both the ancient Chinese mathematicians as well as those of the West, both of which took on various elements of geometry and spatial reasoning for a significant number of their proofs when other tools were not yet available. The development of algebra I see as a chiefly visual and ideographic one, even tangible or malleable one. The development of UML diagrams another. Flow charts another. We have the abacus and Chinese counting sticks, as well. And finally, while poetry is not specifically rigorous, it is efficient in a way that few other communication methods are. And we find a great deal of "visual cue" elements in that field. In physical sciences and statistics, visualization is a very important tool. Mathematical notation itself is largely spatial and visual at scale.
As for legalese, I would argue that legalese is perhaps well designed for experts to be complete, but not for clarity. Comprehensiveness is different that clarity of rigor. And as for philosophy, vocabulary is not enough. And you'll note that some of the best notational systems to arise came from the philosophy departments in working on logical systems. Those are all usually notationally represented using ideographic, rather than natural language forms. And even some Eastern philosophers who wrote very verbosely tended to make their arguments from visualizations in the mind to make their point.
Musical notation, again, has evolved into a spatial, visual notation. A large number of traditional writing systems were ideographic, including ones we now consider alphabetic/phonetic.
