Not that I know of.  I would say, though, that if you write a charting
library, it would be great to separate the display from the layout as much
as possible, so that different backends could be plugged in.  Not as much
as gnuplot, but enough that it would be easy to support different gui
libraries, or direct postscript output.  I'd definitely like to have such a
module available.
