One area we’ve been paying particular attention to recently has been the internet traffic for different web site categories. Our friends over at comScore Inc. collect a wealth of information for “measurement of the myriad ways in which the Internet is used and the wide variety of activities that are occurring online.” Nice alliteration, guys.

Using some of the data they’ve allowed us to share with you, we had the bright idea to stuff it into our most favoritest charting type, the treemap. And what’s better than a chart? Answer: an interactive chart with a toggle button.

You’ll need to know a few things to really Juice the data:

• The map is based on unique visitors by site for August 2007 and November 2007.
• Red means a decrease in unique visitors over that three month time period and green means an increase. Black means there is no change.
• You can click on the category headers to zoom into each category. Click on the category header again to zoom back out.
• We provide two views of the data: the default shows just the top ten sites in each category. However, for nearly all categories, sites outside the top 10 account for over 50% of the visitation in the category (the exceptions were Search, Portals, and Auctions where the top players dominate traffic). A checkbox adds “All Others” and gives you a better sense of the size of each category. You can toggle these two views using the checkbox just below the map.
• Due to some confidentiality restrictions that we’re under regarding the raw data, we couldn’t show other metrics that would really make this visualization sing—but I bet if you contacted comScore, they’d be glad to discuss with you.
• A few tech notes. The treemap is adapted from Josh Tynjala’s capable open-source Flex Treemap component. Site images are provided by Amazon.com’s Alexa site thumbnail service.

So, without further ado, take a gander at our latest liberated data:

There’s so much information here, you won’t have any trouble drawing your own conclusions, but here are a few conversation starters:

• Notice that there was a distinct increase in retail web visitors leading up to the holiday seasons.
• Surprise! eBay owns auctions
• Not too good of a showing for those online gambling sites; travel either.
• Sports traffic is up… but not for the MLB.com site. Oh yeah, baseball season is over.

Enjoy.

Edward Tufte has produced a illuminating video tour of the user interface of the iPhone. The video illustrates Tufte’s struggles to come to grips with the difference between dynamic screen resolution and the resolution of printed paper. Tufte is prone to grandiose pronouncements, like this one:

All history of improvements in human communication is written in terms of improvements in resolution: to produce, for viewers of evidence, more bits per unit time, and more bits per unit area. Slideware is contrary to that history. Trading in reductions in resolution for user convenience or for pitching may be useful in mass market products or in commercial art, but not for technical communications. The solution is not to rescue slideware design; the solution is to use a different, better, and content-driven presentation method. On this solution, see our thread PowerPoint Does Rocket Science—and Better Techniques for Technical Reports — Tufte Nov 10 2006

Somehow, I don’t think the importance of the Gutenberg Bible related to it showing “more bits per unit area.” Quick, count the “bits per unit area.”

It didn’t take bits per unit area to revolutionize communication in the past and it won’t in the future either. The iPhone is a tremendously engaging information device and points the way forward for information displays. Here’s what the iPhone does well:

Maximize screen real estate: Controls are only visible when needed, fading away gently when you are concentrating on content. Tufte furiously neologizes, calling this “computer information debris.” Control junk is more apt, more terse, more Tuftian.

Direct manipulation: As Tufte says: information is the interface. Filtering and choosing should take place in the context of direct manipulation. A good essay on the possibilities of direct manipulation can be found here.

Fun: Above all, information can be fun and engaging to navigate. Tufte condemns Apple’s stock ticker for having “cartoony” and PowerPoint-like displays and offers an improved version (with 5 digits of precision). Apple’s cheery display offers a more entertaining, usable interface for day-to-day usage.

With our empathy for the day-to-day troubles of the business person seeking insight in data, it’s frustrating listening to Tufte. He is clearly an academic, with academic interests and academic timeframes. As much as his work is respected and inspirational within business circles, he makes little effort to enable his message to be implemented.

Good Tufte: Clutter and overload are not an attribute of information, they are failures of design. If the information is in chaos, don’t start throwing out information, instead fix the design.

Bad Tufte: “…the conclusion of sparkline analysis in Beautiful Evidence, where the idea is to make our data graphics at least operate at the resolution of good typography (say 2400 dpi).” http://www.edwardtufte.com/bboard/q-and-a-fetch-msg?msgid=0002NC&topicid=1 *Ed: At least 2400 dpi? Orly?

Mostly right Tufte: “Thus the iPhone got it mostly right.”

Mostly wrong Tufte: “Adobe Illustrator is a big serious program that can do almost anything on the visual field (other than Photoshop an image). Most of my sparkline work was done in Illustrator. Fortunately all graphic designers and graphic design students have the program and know how to use it, so find a colleague who knows about graphic design.” http://www.edwardtufte.com/bboard/q-and-a-fetch-msg?msgid=0000Jr&topicid=1&topic=Ask%20E%2eT%2e

It is heartening to see Tufte engage and connect his mental frameworks to our modern, screen-oriented, graphics-accelerated, not graphics-designed world. But the future of information design and interaction belongs to the iPhone, not the printed page.
