Stacked Chart Within Stacked Chart?

I've got a few layers of data and wanted to know what the best way to go about displaying it would be. I need to be able to create a SNAPSHOT image of this data. I have 5 browsers (e.g Chrome, IE, Mozilla) and in a stacked bar chart have put users (e.g Internet Explorer -> 10 corporate users, 5 personal users, 3, other
                               Chrome -> 15 corporate users, 20 personal users, 4 others

                               Mozilla -> 2 corporate users, 5 personal)

Now within the users, I have sites they went on. So lets say the personal user could either go on Facebook, Twitter or Instagram. Same with the other users. How can I make a chart so that

Internet Explorer -> [10 corporate users -> (5 facebook, 4 instagram, 1 twiitter)], [5 Personal users -> (2 facebook, 3 twitter)], [3 other users -> (2 facebook, 1 twitter)].

Esentially I want to break down the data shown in the stacked chart even further, created a stacked chart within a stacked chart. I don't want to highlight anything, just have it as a picture. Let me know if you have any ideas!
