Another possibility (although it doesn't have any built-in graphics
per-se) is S-lang (http://space.mit.edu/%7Edavis/slang.html) or ISIS 
(http://space.mit.edu/ASC/ISIS/) which is built on top of S-lang and
does have graphics via pgplot.  It's IDL-like but built with a
stack-based model.  It's quite lightweight, and we've been using it as
a command language built inside our X-ray spectral analysis code. 

Without any built-in graphics, S-lang can't be a drop-in replacement
for IDL, but if you've got a project that could really use a small,
powerful, and IDL-like scripting language, S-lang might be useful to
