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.
