Bullet charts are excellent devices for clear data visualization. They have become part of the graphing toolset for a number of dashboard and business intelligence graphing software applications.
Did you know that you can build them yourself for use in Excel?

The first comes from Micheal Alexander of Excel 2007 Dashboards & Reports For Dummies fame.
