Template::Plugin::GD::Graph::lines - Create line graphs with axes and legends

       Thomas Boutell wrote the GD graphics library.

       Lincoln D. Stein wrote the Perl GD modules that interface to it.

       Martien Verbruggen wrote the GD::Graph module.

       Craig Barratt <craig@arraycomm.com> wrote the original GD plugins for the Template Toolkit (2001).

       Andy Wardley <abw@cpan.org> extracted them from the TT core into a separate distribution for TT version
       2.15.

       The GD.Graph.lines plugin provides an interface to the GD::Graph::lines class defined by the GD::Graph
       module. It allows one or more (x,y) data sets to be plotted as y versus x lines with axes and legends.

       See GD::Graph for more details.
