Bubble diagrams are circles or ovals drawn that help the architect identify the location of the rooms to be included in the floorplan for a home or commercial building. A bubble diagram spatial relationship cab represents the flow of space and provides information about the sizes of rooms relative to each other. Spatial bubble diagrams are sketches to help architects identify the areas of the home that will be included in the drawings. These diagrams are used at the preliminary phase of the design process and are used for space planning and organization. The below bubble diagram is created using online tools like EdrawMax and shows the spatial relationship like how the lobby area is connected with the exhibit hall, which in return is connected with a retail store, theater area, and banquet hall.
