Britney Spears Albums

I'm copying Joz's Girls Aloud album post by posting my own graph, Britney Spears-style. I couldn't figure out how to do a line graph so you are getting a bar graph. I think In the Zone has been her best album yet thus far, followed by Blackout, Circus ties with Britney, Oops! I did it Again, and ...Baby One More Time is dead last.
