Gas prices

GasBuddy has an interesting graphic (called a heatmap) that shows the average price of gas around the nation. I would think that, in general, the further you are away from the source of the product (the Gulf mostly) the higher the price would be because of transportation costs. Obviously there are other things in the mix here too though based on this picture; Supply and demand issues and local taxes come to mind.

Another interesting use of heatmaps is shown by some research done by EyeTools that tracked where subjects eyes looked while looking at a Google results page.
