Source code for the book examples for the folks who have kindly purchased the book (lining my pockets, $1.50 at a time).
Chapter 3 (the US map example).
Chapter 4 (time series with milk, tea, coffee consumption)
Chapter 5 (connections & correlations – salary vs. performance)
Chapter 6 (scatterplot maps – zipdecode)
Chapter 7 (hierarchies, recursion, word treemap, disk space treemap)
Chapter 8 (graph layout adaptation)
These links should cover the bulk of the code. More can be found at the URLs printed in the book, or copy & pasted from Safari online. As I understand it, those who have purchased the book should have access to the online version (see the back cover).
All examples have been tested but if you find errors of any kind (typos, unused variables, profanities in the comments, the usual), please drop me an email and I’ll be happy to fix the code.
