# === Base object for generating SVG Graphs
#
# == Synopsis
#
# This class is only used as a superclass of specialized charts. Do not
# attempt to use this class directly, unless creating a new chart type.
#
# For examples of how to subclass this class, see the existing specific
# subclasses, such as SVG::Graph::Pie.
#
# == Examples
#
# For examples of how to use this package, see either the test files, or
# the documentation for the specific class you want to use.
#
# * file:test/plot.rb
# * file:test/single.rb
# * file:test/test.rb
# * file:test/timeseries.rb
#
# == Description
#
# This package should be used as a base for creating SVG graphs.
#
# == Acknowledgements
#
# Leo Lapworth for creating the SVG::TT::Graph package which this Ruby
# port is based on.
#
# Stephen Morgan for creating the TT template and SVG.
