Create area graphs with axes and legends

The \s-1GD\s0.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.
