Processing 2.0 alpha 3 released

Download it here. This is the third alpha release as we head toward 2.0. There are many significant changes in 2.0, so be sure to read up on them.

If you find problems, please file a report so that we can fix them.

The big changes since 2.0a2:

  • Several Android fixes to handle recent SDK changes by Google. For anyone using Android, you’ll need to install 2.0a3. The Android page on the Wiki has also been updated.
  • Fixed a regression in 2.0a2 that prevented serial from working on OS X.
  • Tracked down a problem on OS X 10.7 (Lion) where the mode and open menus on the toolbar disappeared immediately.

The full revisions list with the gory details:

PROCESSING 2.0a3 (REV 0202) – 5 November 2011

Some weekend bug fixing and regression repair for the recent alpha releases.

Also several Android fixes to get things working again with more recent
updates from Google. You’ll need to upgrade to this version of Processing
in order to continue using Android mode.

Book

Visualizing Data Book CoverVisualizing Data is my book about computational information design. It covers the path from raw data to how we understand it, detailing how to begin with a set of numbers and produce images or software that lets you view and interact with information. Unlike nearly all books in this field, it is a hands-on guide intended for people who want to learn how to actually build a data visualization.

The text was published by O’Reilly in December 2007 and can be found at Amazon and elsewhere. Amazon also has an edition for the Kindle, for people who aren’t into the dead tree thing. (Proceeds from Amazon links found on this page are used to pay my web hosting bill.)

Examples for the book can be found here.

The book covers ideas found in my Ph.D. dissertation, which is basis for Chapter 1. The next chapter is an extremely brief introduction to Processing, which is used for the examples. Next is (chapter 3) is a simple mapping project to place data points on a map of the United States. Of course, the idea is not that lots of people want to visualize data for each of 50 states. Instead, it’s a jumping off point for learning how to lay out data spatially.

The chapters that follow cover six more projects, such as salary vs. performance (Chapter 5), zipdecode (Chapter 6), followed by more advanced topics dealing with trees, treemaps, hierarchies, and recursion (Chapter 7), plus graphs and networks (Chapter 8).
