This dataset contains a subset of the fuel economy data that the EPA makes
available on <a href="http://fueleconomy.gov">http://fueleconomy.gov</a>. It contains only models which
had a new release every year between 1999 and 2008 - this was used as a
proxy for the popularity of the car.

A system for 'declaratively' creating graphics,
based on "The Grammar of Graphics". You provide the data, tell 'ggplot2'
how to map variables to aesthetics, what graphical primitives to use,
and it takes care of the details.
