I tried all of them out, but got not each working. This was the reason
I decided to write GD::Graph, which only depends on libgd and the Perl 
libraries GD, GD::Graph and/or GD::Graph3d.

It supports the following diagram types: 
Bars, Lines, Points, LinesPoints, Area, Mixed, Pie, Bars3d, Lines3d and Pie3d

I guess libplot, Ruby/Gnuplot and Ruby/PGPlot are more for scientifical 
diagrams.
