This dataset contains a subset of the fuel economy data that the EPA makes
available on <url>http://fueleconomy.gov</url>.  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.

datasets

An implementation of the grammar of graphics
    in R. It combines the advantages of both base and
    lattice graphics: conditioning and shared axes are
    handled automatically, and you can still build up a
    plot step by step from multiple data sources. It also
    implements a sophisticated multidimensional
    conditioning system and a consistent interface to map
    data to aesthetic attributes. See the ggplot2 website
    for more information, documentation and examples.

Fuel economy data from 1999 and 2008 for 38 popular models of 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.
