Rainer Joswig sent a screenshot of scigraph (158 KB tarball) , a Common Lisp scientific graphing package.
Scigraph is CLIM-based, and supports histograms, line plots, scatter plots, spin plots, and more; it's also designed to be extensible.
(Also see this previous entry on charting and plotting packages.)
