Visualizing Historic Browser Statistics with Axiis

For the beta release of Axiis I prepared a visualization showing the historical browser breakdown of visitors to W3schools.com.  Since then I’ve enhanced it a bit, adding the ability to filter by browser type, and Tom lent his artistic eye and did a little restyling.  Although the number of Axiis tutorials out there is growing [...]

Hit detection on graphics primitives: Speeding up the Parallel Coordinates Plot

In my last post I mentioned that I had rewritten the Parallel Coordinates Plot to achieve a pretty drastic speed up. Before I get into the graphics hit detection trick at the heart of the performance boost, I’d like to explain the problem with the original implementation. The main thing that dragged down the [...]

What I’m doing with my final semester

I’ll be receiving my MS degree in Computer Science at the end of this semester.  I finished my degree requirements last semester, but my timing on some of those requirements was a little funny, so I wasn’t eligible for graduation at the time.  In order to graduate this semester, the University requires that I be [...]

Visualizing the 2008 NFL Season

Super Bowl XLIII is less than two weeks away, so it feels like an appropriate time to look back at the statistics that were so diligently recorded during this past football season.  I’ve put together a comparison matrix based on data from pro-football-reference.com.  For first time visitors, a comparison matrix processes multidimensional statistics, looking for [...]

My app was just on TV

CNN just did a piece on the influx of people into DC for the inauguration.  Several of the tools the CATT Lab has developed are going to be used to help manage the traffic problems that are guaranteed to crop up as a result.
