Exploratory data analysis is the manipulation, summarization, and display
of data to make them more comprehensible to human minds, thus uncovering
underlying structure in the data and detecting important departures from
that structure [4]. A complete data
exploratory system thus has three major ingredients. We have dealt with
display in our parallel coordinates technique, and with summarization in
building the cluster hierarchy upon the data. We now turn to the third
component, manipulations.
