All Streets Error Messages

Some favorite error messages while working on the All Streets project (mentioned below). I was initially hoping to use Illustrator to open the generated PDF files (generated from Processing), but Venus informed me that it was not to be:

I’m having difficulties as well. Why did I pay for this software?

Generally, Photoshop is far better engineered so I was hoping that it would be able to rasterize the PDF file instead, never mind the vectors and all.

Oh come on… Just admit that you ran out of memory and can’t deal. Meanwhile, Eugene was helping out with the site, from the other end of iChat:

Oh well.

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).

This site is used for follow-up code and writing about related topics.
