Visualization + Processing in Today’s IHT

Alice Rawsthorn writes about visualization in today’s International Herald Tribune, which also includes a mention of Processing:

Producing visualization required the development of new tools capable of analyzing huge quantities of complex data, and interpreting it visually. In the forefront is Processing, a software system devised by the American designers, Ben Fry and Casey Reas, to enable computer programmers to create visual images, and designers to get to grips with programming. “Processing is a bridge between those fields,” said Reas. “Designers feel comfortable with it because it enables them to work visually, yet it also feels familiar to programmers.”

Paola Antonelli on visualization:

“Visualization is not simply an evolution of graphic design, but a complete and complex design form that requires spatial, narrative, synthetic and graphic sensitivity and expertise,” explained Antonelli. “That’s why we see so many practitioners – architects, product designers, filmmakers, statisticians and graphic designers – flocking to it.”

The Humans vs. Chimps illustration even gets a mention:

Take a scientific question like the genetic difference between humans and chimpanzees. Would you prefer to plough through an essay on the subject, or to glance at the visualization created by Fry in which the 75,000 letters of coding in the human genome form a photographic image of a chimp’s head? Virtually all of our genetic information is identical, and Fry highlights the discrepancies by depicting nine of the letters as red dots. No contest again.

Book

Visualizing Data Book CoverVisualizing Data is my 2007 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. When first published, it was the only book(s) for people who wanted to learn how to actually build a data visualization in code.

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 the 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).
