Hit the letter z, or click the word zoom to enable or disable zooming.


This project began a very short sketch (a few hours) that I created in 1999 because I was curious about how the numbering works for postal codes in the states.

A detailed description of this project (and source code built with Processing) can be found in my book Visualizing Data.

Updated September 2004 to add several features over the original, including zoom, some new colors (thanks to Eugene Kuo), and a better zip code database (because of all the people who emailed and were sad that they couldn't find themselves).

Rewritten February 2014 to use JavaScript instead of Java.
