The GD.Graph.area plugin provides an interface to the GD::Graph::area class defined by the GD::Graph module. It allows one or more (x,y) data sets to be plotted as lines with the area between the line and x-axis shaded, in addition to axes and legends.

See GD::Graph for more details.

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.
