How do I create a pie plot in a map plot?

I have a dataset about some canteens, the number of people per hour, and their total capacities.

The image provided below shows the map. The bigger the bubble, the more people present.

The image below is a screenshot of my table

With regards to the seating capacities, is it possible to show each bubble on the map as a pie chart to represent the fullness of the canteen? For example in the last row, the capacity is 780 and the number of people is 19. So the percentage would be 19/780. I know this is usually done with binary values, but would it be possible with the way I described?

Or is it possible to plot 2 overlapping different "layers" of bubbles? The first layer is the current number of people, and the second is the capacity. So as the bubble for the number of people gets bigger than the bubble for capacity, it indicates the canteen is at full capacity.

Thank you.
