This zip file contains all the code and data used in Visualize This. Chapters 1, 3, and 9 do not use any code examples. You can download the code and data files in their entirety at Wiley:

. They are also available at

. For many of the code examples, you will need to download R (http://r-project.org). Some require a Python interpreter or a Flash compiler (for example, Adobe Flash Builder).
