By the way, here is the patch to add tikz to draw:

In grcommon.lisp  add $tikz in function update-terminal, that is for 
example:

  (let ((terms '($screen $png $pngcairo $jpg $gif $eps $eps_color $canvas
                  $epslatex $epslatex_standalone $svg $x11 $qt $tikz

..............


and in file  gnuplot.lisp  add in function draw_gnuplot instruction to 
output tikz.

For example after

($gif (format ...(get-option '$file_name)))

add the following, mostly copied from the gif command:

     ($tikz (format cmdstorage "set terminal tikz  ~a size ~a, ~a~%set 
out '~a.tikz'"
                            (write-font-type)
                            (round (first (get-option '$dimensions)))
                            (round (second (get-option '$dimensions)))
                            (get-option '$file_name)))

Then reload draw and you can do:

  draw2d(file_name="~/toto",terminal=tikz,explicit(cos(x),x,1,10));
                        [gr2d(explicit)]

which produces, as asked a file  toto.tikz in your home, containing:

\begin{tikzpicture}[gnuplot]
%% generated with GNUPLOT 5.2p8 (Lua 5.3; terminal rev. Nov 2018, script 
rev. 108)
%% dim. 20 nov. 2022 19:55:06
\path (0.000,0.000) rectangle (600.000,500.000);
