My first stab at visualizing this data was a traditional cartographic approach, showing the overall growth from 1977 to 2006 at each station. This told an approximate story at the level of the whole the city, but did not leave much room for detailed exploration. Thanks to geoserver’s awesome new(ish) dynamic symbolizers functionality, it was trivial to plot the station-by-station time series sparklines (generated in R of course) onto the interactive online map. (Originally I the plots were produced in Perl and placed onto the map with a Javascript WFS layer, but that is so 2005.)

New York City agencies issued 9,955,441 parking tickets from July 2007 to June 2008.

The chart below shows the sample release years in more detail, telling another story. Here, we can see how heavily Gregg uses samples from the last three years, and strongly avoids samples for the previous three-year period from 2001 to 2004. (Too old to be cool, but not old enough to be retro?)

Lots more geekiness around the samples used in Girl Talk’s new album.
