Baby Name Voyager Visualization Again

Some time ago, for a problem we were working on for visualizing initiative data, we looked at the work of Martin Wattenberg.  Probably most famous is his Baby Name Voyager.  This takes social security data of the choice of baby names since the 1880s and cleverly visualizes the results into a highly interactive stacked line chart.  More technical information.  Although we did not use it for the problem at the time, it has come up again as an example for interacting with low dimension,  high volume data.  Worth taking another look, like I did.  Love to hear of other examples of its use.
