This displays a lot of interesting characteristics, but I wish I could explore the data further. For example, zoom in on the 4 years leading up to 2008, then compare to the 4 years leading up to today. Also interesting is that the data is clearly cyclical on an annual pattern. Look at the last 5 years for evidence of that.
