Probably a cleaner and system independent way to tell gnuplot to shut
down is just to close the socket through which commands are sent -- I
don't know for sure, but I suspect that gnuplot will terminate if the
socket is closed, since that is a widely used convention for
organizing interprocess communications.

Maxima (https://maxima.sourceforge.io) is a Common Lisp application
and it has some code to work with gnuplot for plotting; see
src/plot.lisp and src/gnuplot_def.lisp (I think those are the right
file names) to get some ideas about how stuff was handled there.

best,

Robert
