Graphs for conditional items

    Hey there, quick question:
    Let's assume I have fictitious 3 variables:
    • 2 Points in Time (for example: 2020 and 2021)
    • Drinks coffee (yes/no)
    • If person drinks coffee, do they add milk? (yes/no)

    The last item depends on the answer to the previous question.

    Now I would like to compare 2020 to 2021, while also looking at the conditional "adds milk" aspect.

    Let's use fictitious data:

    5000 coffee drinkers (CDs), 6400 non-coffee drinkers
    Of those 5000 CDs, 3000 said they add milk.
    We obviously have no data on Non-CDs, since they did not answer the Coffee question with a "yes",

    6100 coffee drinkers, 7800 non-coffee drinkers
    Of those 6100 CDs, 2200 said they add milk.

    How would I best illustrate something like this in one neat, tidy graph?
    Or perhaps, how do I need to handle this kind of data in general?
    I probably need filter variables for the calculations themselves, right?

    Thanks in advance.
