ABSTRACT
In this chapter, we present several methods for visualizing and exploring multivariate data. We have already seen some of these methods in previous chapters. For example, we had grand tours and projection pursuit in Chapter 4, where the dimensionality of the data is first reduced to 2-D and then visualized in scatterplots. The primary focus of this chapter is to look at ways to visualize and explore all of the dimensions in our data at once.
