A theoretical model for pattern discovery in visual analytics

The word 'pattern' frequently appears in the visualisation and visual analytics literature, but what do we mean when we talk about patterns? We propose a practicable definition of the concept of a pattern in a data distribution as a combination of multiple interrelated elements of two or more data components that can be represented and treated as a unified whole. Our theoretical model describes how patterns are made by relationships existing between data elements. Knowing the types of these relationships, it is possible to predict what kinds of patterns may exist. We demonstrate how our model underpins and refines the established fundamental principles of visualisation. The model also suggests a range of interactive analytical operations that can support visual analytics workflows where patterns, once discovered, are explicitly involved in further data analysis.

Automated summary

This article discusses the definition of "pattern" in data visualization and visual analytics, proposing a practical concept definition. Patterns are formed by relationships between data elements, and understanding these relationships can predict possible pattern types. The model supports and refines established principles of visualization.
