Data visualization and educational efficiency

January 12, 2013 by


Can data visualization be used in the classroom? I recently stumbled on some research suggesting that presenting information visually may have significant benefits over text-based materials. The BBC reports that interpreting visual data requires fewer cognitive resources than reading texts. The results showed that when tasks were presented visually rather than using traditional text-based software […]

Strangers in Paris: census maps, layering, and data compression

April 20, 2011 by


I have been working on a blog series on census data visualizations for another site (which will be reproduced here when it’s all up). First of all, I am using that as an excuse to justify how little I have been posting in the last couple of weeks. However, there is also something I could […]

Visualizing a Public Good

March 25, 2011 by


Have you ever been waiting for a bus for half an hour, only for two half-filled buses of the same route to roll up to your stop?

AAAS Visualization Challenge

Data visualization isn’t limited to the social sciences. As a case in point, the American Association for the Advancement of Science (which publishes the journal Science) recently held a competition for data visualization. There were some really cool ideas – a team from MIT tracked where pieces of trash ended up, a Russian team created a […]

Eckstein’s fantastic blog, All My Eyes.  Her post uncovers a set […]

Public Debt and GDP

February 16, 2011 by


Which countries have the greatest public debts relative to the size of their economies? The IMF has a great data mapping tool, which includes the ability to look at historical data and play back changes over time. The following graph comes from their historical public debt database; the graph below was adjusted using PPP. The […]

Visualizing predictive crime maps

February 10, 2011 by


Crime mapping has been a tool employed by police for more than a century, but only recently has the data collection been organized and consistent enough to accurately aggregate spatial crime statistics. I was taking a look at a 1997 paper on predictive crime mapping using artificial neural networks—a topic I recently became very interested […]
