Multivariate Mapping

Multivariate mapping is the visual exploration of multiple attributes using a map or data reduction technique. More than one attribute can be visually explored and symbolized using numerous statistical classification systems or data reduction techniques. Complex data relationships can be visually displayed using graphical symbols. Color encodings are used to represent spatial relationships in a given data set in a logical sequence and interpretable format. To successfully communicate these complex spatial relationships, serious attention must be paid to human cognitive factors and perception. In practice, most small-scale data sets are usually displayed using graduated colors, graduated symbols, proportional symbols, dot density, bar charts, and stacked charts, among others. More recently, large-scale data sets have been represented using more complex data reduction techniques.
