Data visualization and educational efficiency

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 […]

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 […]

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.

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 […]
