Is there a flowchart with a DAG of the different branches of mathematics? I'd like to dip my toes into some specific areas of mathematics (like Category Theory) and my problem is that I did not find a flow chart which displays how different branches of mathematics depend on each other so I can narrow down the topics I need to look into.
I've found this question but the links in the answers are either broken or useless.
Having a flowchart like that would be immensely helpful for a lot of people. Is there such a thing? If yes, where?

If you coarse grain your areas of mathematics like as broad as "category theory" then there will be parts were you need a certain prerequisite and parts where you don't. This means you will not really get a DAG anymore.
Say you have A is a prerequisite for B for C for D. Simple example. But A and C are both treated as parts of the subject 1 and B and D as parts of subject 2. You now have a loop where both subjects require each other.
Because these broad subjects have lots of parts that are interconnected with each other like this, you won't be able to have a directed system if you want such broad branch titles. If you go with the very specific parts, then you might be able to build a flowchart, but it will be too big to be useful.
