Baseball

Note that you can set just about everything yourself on the chart below. There are also three different visualizations to choose from which can be selected at the top right.

I would suggest setting both the Y-Axis and Size to Payroll in 2011 USD and colors to unique colors. Setting opacity in the tools at the lower right to 0% also helps - that way you can select just the teams you're interested in and get a cleaner plot. I'm trying to work how to make it default to these, but Google seems to have largely abandoned the motion chart, so it's a bit complicated.

Anyway, play with the settings, click on things, etc.
