This chapter introduces the concept of visual correlation and describes the essence of a generalized correlation to be used for multilevel and conflicting data. Several categories of visual correlation are presented accompanied by both numeric and non-numeric examples with three levels (high, medium and low) of coordination. We also present examples of multi-type visual correlations. Next, the chapter provides a classification of visual correlation methods with corresponding metaphors and criteria for visual correlation efficiency. Finally, the chapter finishes with a more formal treatment of visual correlation providing formal definitions, analysis, and theory. Key words: Visual correlation, heterogeneous data, visual data mining, information visualization, glyph, metaphor, classification, guidance, distortion, formalization, homomorphism, relational structure.
