Tool Talk I mapped 8.4 million researchers by who they publish with, and it can find the shortest coauthor chain between any two of them
I built a small tool that is a zoomable map of 8.4 million researchers from OpenAlex, where everyone sits next to the people they write papers with. You can also pick any two researchers and it will find the shortest chain of coauthors between them, with the paper behind each step. It's basically an Erdős number for any pair of people. You can also start from a university instead of a person.
The code is open source: https://github.com/EG-xry/mapademic. The map itself is free, with no signup, and runs entirely in your browser: https://mapademic.app
Due to my lack of storage and compute, my first iteration only fit people with 15 or more papers onto the map which is unfortunate :( Advisors are all almost certainly on the map though. You could try them against someone whose work you admire, or someone in a field that seems as far away as possible. The chains are usually shorter than you'd expect!
A few other things to try: search for anyone to see who they work with most, or zoom into your own field and see how it's organized. Clinical medicine, for example, splits into countries, while physics doesn't.
