Bubble Diagrams

I'm currently planning the condo layout for a school project, which involves planning adjacency and spatial relationships. This is primarily done using an adjacency matrix and bubble diagrams.

Bubble diagrams represent rooms in approximate scaled size, but more importantly determine location with other rooms in the space. They are meant to be fast, messy, exploratory, and easy to crumple up and start over. My prof recommends completing them on trace paper for this very reason!
Bubble diagrams are on the NCIDQ exam, so if you want to be a licensed interior designer, you need to know them!
Even though they aren't intended to be pretty, I think there is something absolutely darling about these diagrams. Don't you?
