Put a dot on the map for each data point, or colour regions if that’s how the data is.
Given this is effectively one piece of data (% of income on rent) you can colour it on a scale. A red dot is 100% on rent. A green dot is 0% on rent. Colours in between represent middle states.
I actually prefer this though, easier to see detail instead of having to compare shades of colours, our brains have issues with that sometimes. (This can be avoided with a good colour scheme I guess?)
Greatly prefer this as well. It’s a lot easier to tell the difference between 50 and 75% with a pie chart than it is with your eyeballs looking at how similar or different two colors are.

It’s great for detail, but bad for getting a general look. Could get busy with more data points.
I think it’s a good choice for this particular map, but I could imagine a different map with more cities which would be a bad choice for pie charts.
