For readers who love data - and the visual representation of data - this site from statistician Nathan Yau will provide hours of brainy entertainment. Readers may like to scout the site by Categories, such as Visualization (Seeing data), Statistics (Analyzing data), and Maps (Seeing geographic data), among others. They may also explore Recent data representations, which, at the time of this writing, included a lottery simulator, an analysis of the character appearances in the classic romantic comedy Love Actually, and a visual representation of all 1,942 currently known exoplanets. There are also excellent Tutorials, such as How to Make an Interactive Bar Chart with a Slider; however, these require a monthly membership with FlowingData, for a $5 per month fee.
