That's also what I do for one of my projects. I tried GD::Graph and
Chart::Graph::Gnuplot and wasn't happy with either.
GD::Graph only allows you to graph two datasets when using two y axes.
Chart::Graph::Gnuplot, which is a wrapper around gnuplot, has an unwieldy
interface and makes it difficult to use some features of gnuplot.
