1. A non-transitory computer-readable medium storing a program for interactive data mining including programming instructions for: reading in a set of data vectors wherein each data vector comprises a class attribute, and a plurality of additional attributes; counting a plurality of counts of times each particular attribute of said plurality of additional attributes, takes on each of a set of possible values for the particular attribute; and presenting a plurality of histograms on a computer display wherein each of said plurality of histograms includes counts for one of said plurality of additional attributes versus attribute value and wherein said plurality of histograms are presented in a sorted order; wherein said sorted order is based on a sorting-of the histograms according to a metric of non-randomness of distributions shown in said histograms; wherein the metric of non-randomness is a metric of discriminative power with respect to said class attribute.
