What Is Bubble Diagram?
A bubble diagram is analogous to a wedding reception layout. When planning the layout of a formal wedding reception, it is common to see the location of the head table for the wedding party, the cake table, the dance floor, the band area, and each guest table for specific guests. A diagram is created to show where each of these will be located within the reception venue so that it can be adequately implemented at the time of the event. Each of these items is depicted in the diagram with shapes, like circles or squares, placed in their designated arrangement within the venue. Bubble diagrams have this same purpose in the field of architecture and interior design in that they show the arrangement and placement of spaces, while also showing the relationship between them. Specifically, bubble diagrams have drawn bubbles (representing spaces) that are connected by different types of lines that indicate the type of relationship between the spaces.
Bubble diagrams are hand drawings made by architects and interior designers. They are important to create at the preliminary phase of the interior design process in order to effectively get to the end phase, which is dependent on these diagrams. Since the main purpose of bubble diagrams is to portray the organization and relationship of spaces, they are useful in designing function but are not a part of aesthetic design. This is because aesthetic design involves more of the senses, how something looks, feels, etc, which can involve color, pattern, balance, and movement. Thus, architects and interior designers do not use bubble diagrams to create aesthetic buildings and interior spaces. Working with bubble diagrams will not result in an aesthetic building but a functional one. The functionality of the building or interior space is the ultimate goal for bubble diagrams.
Bubble Diagram in Architecture
As discussed in the previous section, design principles can involve functional-usability and aesthetic-usability. In architecture, bubble diagrams convey information regarding functional-usability specifically by depicting the following elements: the spaces of the building, their functions, relationships, and the circulation patterns. These elements are described in further detail in the subsections below.
Program in Architectural Design
In interior design and architecture, the program is a list that itemizes the spaces that must take place in the building. It outlines the building requirements while itemizing and providing a description of each space with its assigned square footage, description of function, and use or activities, for all spaces.
The program is the main purpose of the bubble diagram. Programs can be used in interior design bubble diagrams just like how seating charts are used in mapping a wedding reception. Like a seating chart helps to translate the list of attendees into table arrangements, a bubble diagram helps to translate the program into a strategy or form. Essentially, the bubble diagram helps the designer to graphically illustrate the program for space planning and organization purposes dedicated to creating functional buildings and interior spaces.
Bubble diagrams depict a program with the use of circles and ovals in a floor plan format. Each bubble (circle or oval) represents the space in order to serve its function (such as dining or sleeping) to create functional aspects of design, such as privacy, circulation, noise, and daylight. The bubble diagrams also convey which functions (circles or ovals) should be near one another in order for there to be functionality within the building.
The example of the seating chart used for wedding mapping can also be used to illustrate the concept of spatial relationships. For instance, when planning where to place the head table and the cake table at the reception, one could plan to place them near each other. This would be feasible because the bride and groom, seated at the head table, would need to go to the cake table as part of the ritual during the reception. This is similar to when planning the initial stages of home design. The kitchen may be placed closest to the dining room because food preparation and eating are compatible functions. The way this functional relationship would be illustrated on a bubble diagram would be adjoining or intersecting circles for the kitchen and dining room.
Adjacency and Proximity in Spatial Relationships
The previous section touched on two important concepts in spatial relationships, adjacency, and proximity. Both concepts are used in bubble diagrams to express the relationships between spaces in a building. Adjacency defines the common needs, working spatial relationships, and their relative importance. In bubble diagrams, adjacency is expressed graphically and written with keywords, such as "primary, mandatory, secondary, desirable, or undesirable".
Proximity specifies the closeness of one space to another. In bubble diagrams, proximity relationships between spaces are arranged and communicated with keywords, such as "immediate proximity, and convenient proximity".
When considering the relationships between spaces, there is another concept that involves the flow of movement from one space to another. This concept is called circulation. It involves the entry and exit points of spaces, how the spaces relate (directly or indirectly) to one another in this regard, and the patterns of movement. Corridors, aisles, stairs, etc are all a part of circulation. In bubble diagrams, circulation is another important concept used where indications about the desired circulation should be included and connections between the various spaces are expressed as "must have, should have, or nice to have".
Use of Graphical Language
Designers are free to use any graphical design or language since there is no accepted professional standard used in bubble diagrams. Lines, arrows, circles, and ovals make a few graphic conventions for the bubble diagram that are used universally. There are no lists of symbols for the bubble diagram. In general, bubbles (circles and ovals) are varied in size, shape, and color.
Freehand drawings are conventional tactics that allow quick-expression, multiple layouts, and multiple revisions. Designers many times size the bubbles relative to one another, like a small circle for a bathroom and a large circle for the living room. However, since this is not a standard and bubble diagrams are personalized by each designer with his or her own symbols, a legend or key is useful in order to explain the bubble diagram.
Architects and interior designers use a bubble diagram for space planning and organization and to create functional buildings and interior spaces. Bubble diagrams graphically illustrate the program, which is a list that itemizes the spaces that must take place in the building with their assigned square footage and description of function, use or activities. The program is the main purpose of the bubble diagram that can be used in interior design bubble diagrams. In architecture, bubble diagrams will not result in an aesthetic building but a functional one, as functionality is the ultimate goal for bubble diagrams. At the preliminary phase of the design process, bubble diagrams depict only the elements dealing with building functionality (or that make the building use efficient), such as the spaces of the building, their functions, relationships, and the circulation patterns.
One key element, the relationship between spaces of the building, is expressed in bubble diagrams by the concepts adjacency and proximity. Adjacency defines the common needs, working spatial relationships, and their relative importance, while proximity is the closeness of one space to another. Another key element, circulation, involves the flow of movement from one space to another. Overall, designers can use any graphical design or language, as there is no standard. This enables the bubble diagram to be personalized by the designer. There are no lists of symbols for the bubble diagram. Generally, in bubble diagrams, lines, arrows, circles, and ovals are used universally, and circles and ovals vary in size, shape, and color.

How do bubble diagrams work?
Bubble diagrams show the arrangement and placement of spaces while also showing the relationship between them. On the diagrams, drawn bubbles (representing spaces) are made and connected by different types of lines that indicate the type of relationship between the spaces.
How do you make a bubble diagram for interior design?
In interior design, a bubble diagram helps to translate the program (an itemized list of spaces with a description) into a strategy or form. Essentially, the bubble diagram helps the designer to graphically illustrate the program for space planning and organization purposes.
