Information Visualization [chapter]

Daniel A. Keim
2005 Exploring Geovisualization  
In this article, we provide an overview of information visualization and visual data mining techniques, and illustrate them using a few examples.  ...  Never before in history has data been generated at such high volumes as it is today. Exploring and analyzing the vast volumes of data has become increasingly difficult.  ...  Visual data mining techniques also need to be tightly integrated with the systems used to manage the vast amounts of relational and semistructured information, including database management and data warehouse  ...
