Mets Historical Win Graph courtesy of Amazin' Avenue I love it when graphs like this are labeled, it makes it much easier to follow especially for someone who lacks historical knowledge of the team. I mean its not perfect, I think the peak in the middle of the 80's is ripe for a picture of a big pile of cocaine along it, but that may be pushing the boundaries of tastelessness. But that's probably a question better left for Keith Hernandez (HIYOOOO!)
From Marquez67 of Athletics Nation post on the Athletics win history. Nothing hugely scientific, but I'm a big fan of visual aids in modeling data.
