    # === 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.
