TITLE: Mathematics - The big picture
QUESTION [35 upvotes]: My knowledge in math sums up to several university level courses and a lot of self-study.
Sometimes it feels like Mathematics is a huge subject with a lot of different areas which some of them correlate with each other.
I've tried to find some sort of knowledge map, or interaction map between different areas inside math, but could not find.
I'm asking for this kind of map, paper, or anything which will be a kind of a big picture about current mathematics development, including all current areas and the known interaction between those.
Also, it will be great to see a sketch, map or something about math pyramid. i.e. a map which describes Reliance between math areas and the existence of areas based on other.
THANK YOU!

REPLY [3 votes]: Have you seen the cool "MSE-driven" graphs of maths (well ... of MSE question tags) posted on meta? They only include the 64 most popular tags, so a lot of more advanced and/or specialised areas are left out, but I still think they provide some insight.
