Graph theory - it has an immense amount of overlap with computer science.

Sure, but is there work in graph theory outside of academia? Obviously there are people who use it to solve real problems but I'm unsure if you can really get a job as a graph guy.

It depends, when I worked at a big company that produced a CAS (computer algebra system) they had an entire team for building graph theory ideas into the software. When I worked at a startup working on urban traffic congestion, there was just one guy who had done some surface-level reading one weekend on max-flow-min-cut and some basic algorithms. Knowing graph theory definitely helped me get that startup job (and take over as "the graph theory guy")

Actually, now that I think about it, I am giving you quite a microcosmic example. I agree that coming across graph theory jobs is tough, but its still worth knowing, at least at a surface level.
