New Data Visualizations

One of my enduring interests is data visualization. It hits so many user experience hot buttons: cognition, potential for confusion, Gestalt principles, and so forth. Research in the past few years seems to have slowed considerably in this area, perhaps because much of the breakthrough work has already been done. We're not seeing new methods of visualization now, but refinements of old ones. Fisheye views (PDF) have been around for a very long time now. So have heat maps, tree maps, network maps, and so on. They're just getting new treatments and makeovers. If you want to see how a lot of them have been retooled with modern computing power and pretty colors, check out this article in the online zine Smashing.

Most of the applications are intriguing and professionally done, but I'm not seeing anything that makes me sit forward in my chair. Many old standbys have been dusted off, like the radar chart, but everything here has been done elsewhere. I don't suppose there are many more visualization methods to be discovered. But the flip side of this is that these techniques are getting more common and less expensive, and therefore more accessible to us. I've wanted to do tree maps forever, but no client has ever warmed to the idea. If you want to see how the principle can be applied well, if a bit understated, look at the daily stock market data here.
