An architectural bubble diagram is a system of lines and circles used in architecture to show relationships between functional areas of a program to develop an architectural plan. Bubble diagrams depict architectural bubble diagrams in circles and ovals in a floor plan format. Each bubble represents the amount of space needed to carry out a specific function, such as dining, sleeping, or studying. Bubble diagrams are line and circle systems used in architecture to demonstrate the relationships between functional areas of a program to develop an architectural plan. Bubble diagrams are rarely published alongside architectural projects, making their presence imperceptible and tracing influence and diffusion difficult.
