LA Politics - can I get a map?

I have lived here for 5 years - I still feel like newbie. Every other city I lived in there was a clear understanding of how politics worked and who controlled what. I’m genuinely still confused with LA. LA city council, LA mayor and then there is Beverly Hills, weho, Santa Monica, Culver City, etc. plus LA supervisors, etc.

Does anyone have a family tree-esque structure to show the political structure and what cities in LA county vote for what positions for all LA county? I understand for mayor and council it may be difficult because council seems to have more power.
