=head1 DESCRIPTION

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 L<GD::Graph> for more details.
