Size, color and position of each of the minor nodes within a major node and size and position of each the major nodes within the squarified tree map is specified so as to produce a visual display which is highly appealing to the visually perceptive/intuitive processes of the human mind therefore enables rapid managerial response to visually perceived, intuitively sensed deviations from selected performance criteria.
