Zack Abrahamson, the "data whiz" at political analysis site Politico, is apparently an R user. Politico's Feb 10 2012 chart of the day clearly uses the ggplot2 graphics package and (quoting Politico)

looks into the disenchanted slice of the GOP that’s not engaged with its party’s primary. And that slice doesn’t like Mitt Romney. People say turnout's down. When it's down, we actually see Romney stronger. [Minnesota is an exception.] This is a general election problem because the people who don't show up today won't show up in November. It’s the CPAC base. Here’s a chart comparing the change in turnout from 2008 to 2012 against the change in Romney support.

Those counties that had higher turnout in the 2012 primaries than in 2008 were associated with a comparatively lower support for Republican presidential candidate Mitt Romney. If I were to nitpick, the legend and color coding is a bit redundant here but, still: it's nice to techniques like small multiples, scatterplots and trensdlines used for political analysis.
