Around 2010 I tinkered with partitioning of disks and other figures into slices and made a word clouds with info like that. There's the Mathematica question how to do that on SE if someone's interested, or I can dig it out (although by now there's millions of web app if you just want the result).
For a finer grained division of math subjects into topics within the fields as well, there's the subject classification for papers etc., there's the MSC2010
https://mathscinet.ams.org/msc/pdfs/classifications2010.pdf
It has thousands of items.
