> The "graphical linear algebra" makes a good case with a larger blast radius, for example. However even that has nowhere near the impact of, say, Feynman diagrams. These are sort of the same example! They're both string diagrams (https://en.wikipedia.org/wiki/String_diagram https://en.wikipedia.org/wiki/String_diagram), just in different monoidal categories.
