Google Underwater

So that might not be the awesome name that they’ll be using, but CNET is rumormongering about Google cooking up something oceanographic along the lines of Maps or Earth. Their speculation includes this lovely image from the Lamont-Doherty Earth Observatory (LDEO) of Columbia University.

Unlike most people with a heartbeat, I didn’t find Google Maps particularly interesting on arrival. I was a fan of the simplicity of Yahoo Maps at the time (but no longer, eek!) and Microsoft’s Terraserver had done satellite imagery for a few years. But the same way that Google Mars shows us something we’re even less familiar with than satellite imagery of Earth, there’s something really exciting about possibility of seeing beneath the oceans.

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).
