gnuplot can do this.  Depending on how gnuplot is built, it will 
likely require X11 libraries, but I don't think it will insist on 
opening an X11 display.

galens at toto:~$ cat gnuplot_cmds
set terminal gif
set output 'sin.gif'
plot sin(x)
galens at toto:~$ gnuplot gnuplot_cmds
galens at toto:~$ ll sin.gif
