    producing friendly error messages so that your users know what's gone
    wrong.

Create Elegant Data Visualisations Using the Grammar of Graphics

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.
