Simple 2D graphics on OSX

What's a simple way to do simple 2D graphics on OSX?

Simple, as in "10 HGR2: HPLOT ...", not 'simple' as in 600-line framework wrappers &| D0InG 1T tH3 CyB3RsPaC3 W@Y dRaGgInG 3D gUi W1Dg3tS aR0U|\|D iN @N INt3rFaC3 BuIlD3R.

Suggestions using the supplied interpreted languages are fine (Perl, Python, etc.)

I found an answer to my problem: libSDL.
The coding for it is relatively straight-forward, and I've used it before on Linux. Got it installed via DarwinPorts.
