How to show the distribution inside a bar?

I’m trying to achieve something similar to a Stacked Bar Chart but I would like to show the distribution inside the bar based on a different value than the value of the population.

Here is an example inside my own notebook (very much work in progress). In my case, I want to show the distribution of the number of respondents inside the bar. Not sure if I’m going in the right direction but the bar should be faceted?

Basically, this would create a third dimension inside the bar chart. I hope I’m explaining this right.
