NY Times on 2009 Subway Ridership Interactive Map

Sometimes I feel like this blog is a booster for the New York Times Interactive Graphics team but it is difficult not to write about such great examples of interactive data visualizations.  Today's map is most likely only of interest to dataviz geeks and New Yorkers.  It is a simple visualization of the subway ridership numbers for last year by station. It accompanies an article explaining some of the huge swings and how they correlate to the local economy.  Let me know what you think.
