Following the first edition (2006), the Indian edition (2008) and the Korean edition (2009), we are glad to announce the new-and-improved 2nd edition. In this edition we've added a set of chapters on forecasting time series, as well as a full chapter on data visualization with an emphasis on data mining and on interactive visualization. A new case, new datasets, and new chapter exercises are also available. Readers with short attention span will enjoy the chapter summaries at the beginning of each chapter. First edition users will notice the nicer design of the new edition.
