# = Description
#
# This object aims to allow you to easily create high quality
# SVG[http://www.w3c.org/tr/svg bar graphs. You can either use the default
# style sheet or supply your own. Either way there are many options which
# can be configured to give you control over how the graph is generated -
# with or without a key, data elements at each point, title, subtitle etc.
#
# = Notes
#
# The default stylesheet handles upto 12 data sets, if you
# use more you must create your own stylesheet and add the
# additional settings for the extra data sets. You will know
# if you go over 12 data sets as they will have no style and
# be in black.
