What term describes a collection of forms grouped together by proximity or a shared visual trait?

The term that describes a collection of forms grouped together by proximity or a shared visual trait is "clustered." In architecture and design, clustering emphasizes how individual elements can create a cohesive composition through their arrangement. This approach often leads to a sense of unity or harmony within the group, allowing for a more organized and aesthetically pleasing design.

When forms are clustered, they may appear as a collective entity, drawing attention to their relationships and interactions. This concept can be applied in various scales, from small details in a room to larger urban configurations where buildings or spaces are positioned closely together based on functional or aesthetic considerations.

In contrast, options like centralized, radial, and grid each refer to different organizational strategies that do not specifically emphasize proximity or shared traits as primary characteristics. Centralized typically refers to a single focal point in design, while radial implies elements arranged around a central point. A grid denotes a systematic layout of intersecting lines, focusing on order and division rather than clustering by visual traits or proximity.
