About This Chapter

In this chapter we take a step back from data mining algorithms and techniques and focus on the visualization of data. This step is crucial and normally takes place before any data mining algorithms have been applied or pre-processing techniques, it is useful because it helps us in some situations pinpoint which algorithms should be used in future analysis. This chapter is divided into three main sections, the first section introduces you, the reader to visualization, the second defines general concepts that are pertinent and the third section explores a couple of visualization techniques
