A business analyst constructs a model they would like to review with key business stakeholders but decides to review the model first with the data scientist who has performed the data analysis. The data scientist provides some suggestions on how to reduce the complexity in the model. One suggestion is to use color to group objects needing to be associated.
The data scientist is encouraging using which Gestalt Principle of Perception with regards to data visualization?
The Gestalt Principle of Similarity suggests that objects that are similar are perceived to be more related than objects that are dissimilar. Using color to group objects that need to be associated is a clear application of the similarity principle. By assigning the same color to related objects, the data visualization helps users visually and quickly identify connections or relationships between those objects.
Page 66 - Apart from these basic principles on visualizations, analysts should be well versed in the design concepts and frameworks for visualization. For example, a good visualization might include 6 core principles from Gestalts' theory of design: proximity, similarity, enclosure, closure, continuity, and connection.
