Advances in acquisition hardware, storage capacity, and personal computer processing speed have made it possible to readily acquire and process enormous sets of data. Large datasets, particularly those with multiple dimensions, can be difficult to analyze and present with standard numerical techniques. Combined with tools to exploit color and brightness to highlight statistically important features, images provide an effective means of displaying this information. The article discusses technical and practical aspects of using images for conveying information.
