Here's another one. I selected for a "six-year graph" and you can see how the average per-gallon price in the U.S. and Canada has doubled in that time. (If the page does not come up as the six-year graph, you have a choice for various time periods on a menu on the page.)

This is, I think, frequently updated data. I just wish it had a 30- or 40-year axis, because the trends going back that far would be extremely interesting to look at.

Joel, you are right - that second graph would be great if it had a longer time frame of comparison. I also like that you can select individual cities in that second graph. While the trend across the board is pretty much the same, it's still interesting to compare cities, especially in different parts of the country.

Here's another aspect of the picture: the commodity price of light-crude oil - the raw material for gasoline, deisel, heating oil, and jet fuel.
