salary vs. performance

What baseball teams are spending their money well,
and how does it change over the course of the season?

Sorry, the 2007 version of this project is currently unavailable.
Check out the 2005, 2006, or 2008 versions instead. To view this content, you need to install Java from java.com

This sketch looks at all 30 Major League Baseball Teams and ranks them on the left according to their day-to-day standings. The lines connect each team to their 2007 salary, listed on the right.

Drag the date at the top to move through the season. The first ten days of the season are omitted because the rankings to (at least) that point are statistically silly. You can also use the arrow keys on the keyboard to move forward or backward one day.

A steep blue line means that the team is doing well for its money, which reflects well on the team's General Manager. A steep red line implies that the team is throwing away money. The thickness of the line is proportional to the team's salary relative to the others.

Updated May 5th for the 2007 season. More background on how this works can be seen on the page for the 2005 and 2006 versions of this piece.

Updated June 5th to add the newer logos for Arizona and Kansas City. My apologies to fans in both locations.

Updated October 12th to fix an error with the number of days. Thanks to Matt Keveney for bringing it to my attention.

A description of how this project works, along with all its source code and the methods used to grab the data, can be found in Visualizing Data, a book I wrote for O'Reilly that will be available mid-December 2007.
