Recently, I had to opportunity to help J. Warren York, a graduate student in the Department of Politics here at UVa. He’s looking at how tax law affects political contributions and advocacy, so this was an interesting project that may tell us something useful about how the US government works [insert your favorite broken-government joke […]
As a teacher, I’ve always operated on the assumption that students are primarily interested in each other. Here’s a fun activity that takes advantage of that interest to teach students a little about data visualization. It’s an extremely unscientific Cosmo-style quiz, designed to show students which interests they have in common with each other. It’s […]
During graduate school I visited my fair share of archives. Living on funds dispensed from the FAFSA gods in combination with whatever part-time job I had, I often found myself hard-pressed to pony up money for photocopies. Somewhere along the line I got smarter and started using a point and shoot camera to gather as much primary […]
[…]Until recently, the collection and maintenance of this structured data was a completely manual process. For years, overnight contractors have entered recipes, dropdown by dropdown, into a gray and white web form that lives in our content management system (CMS).

From the post: A little bit of knowledge about GIS and geospatial visualization goes a long way, and is useful across a variety of disciplines, including social sciences, business, humanities and environmental studies and sciences. If you are into open data (who isn’t?) and you like maps and / or data visualization (who doesn’t?!) […]

Thankfully I was able to find one in the Internet Archive from just a couple weeks after its release, in January 2006. I then took that opportunity to put that code online and […]
From the post: Git is an excellent tool for collaborative software development in a number of ways. In my opinion, Git’s most valuable feature – which also happens to be one of its most underappreciated – is interactive staging: git add -i and git add -p. If you are a software development who does not […]
Because my last tutorial, The Complete n00b’s Guide to Mapping in R, received a positive response, I decided to create another beginner’s guide to visualizing data. For this edition, I’ve chosen Gephi, an excellent and simple tool to do social network analysis. This tutorial is meant to get you started quickly and provide the basics […]

I’ve been playing with Tate’s collections data while preparing for a workshop on data visualisation. On the day I’ll probably use Google Fusion Tables as an example, but I always like to be prepared, so I’ve prepared a short exercise for creating simple graphs in Excel as an alternative.
