Information visualization is the process of uncovering fundamental relations in large volumes of data, which will support insight into them. This book focuses on the problem of creating effective and accessible methods to do this. Many people and institutions possess considerable volumes which may 'hide' some fundamental relation which could be exploited to advantage: estate agents, banks, medical researchers, fraud investigators and many others would like to be able to view some graphical presentation of that data and perhaps interact with it and, at some point, be able to say 'Ah Ha! Now that is interesting!'
