Could you add a way to check that gnuplot is installed? Currently, the only way I can see is to create a Figure, then try to show it or write it to a file. It would be nice if I could get my program to fail fast if gnuplot is not installed, before it gathers and processes a lot of data.
Maybe a possibility is to have Figure::get_gnuplot_version() return a Result<GnuplotVersion>.
