Inspired by this, I thought I would do my own take on this idea.  The plot below shows each of the 8 NFL divisions with the AFC on the left and the NFC on the right.  The height of the bar in each square is the number of wins for that team in that season. If the team made the playoffs, the color is saturated; if the team missed the playoffs, the colors in the square are faded.

Cheers.
