Any suggestions or references on how I might go about charting/displaying political tensions between 6 player characters' home regions?

So I'm creating a pretty convoluted boardgame where each player is a representitve of one of 6 regions on the board, and one of my gameplay elements centers around the concept of civil unrest which logs the tension between and within regions with 1-3 being peaceful, 4-5 being uneasy, and 6 being all out war (or civil war should one's own civil unrest max out). What might be the most optimal way to keep track and convey this information for all player's to see and understand? Are there existing boardgames that do something similar and how do they incorporate this kind of mechanic into the game at large?
