Which diagram is primarily used to map spaces by function and adjacency relationships without requiring exact dimensions?

• A. Bubble diagram
• B. Gantt chart
• C. Floor plan
• D. Budget sheet

Answer: (A)

Mapping spaces by function and adjacency without exact dimensions is best done with a bubble diagram. This type of diagram uses simple shapes to represent different spaces and focuses on how they relate to one another—which areas should be near each other, how they connect, and how circulation might flow between them—without locking in precise sizes. Because there’s no need for exact measurements, you can experiment freely with layouts, testing options like which rooms should be grouped for easy access or which paths should guide movement through the space.

Other diagrams serve different purposes. A Gantt chart tracks tasks and timelines, not physical relationships between rooms. A floor plan shows exact room sizes, wall locations, doors, and fixtures, requiring precise dimensions. A budget sheet handles costs rather than spatial organization.
