It should be

htlatex  graphics.tex "hej,2,mathml,charset=utf-8" \
      "-cmozhtf -utf8" "-cvalidate"

or

make4ht -uc hej.cfg graphics.tex "2,mathml" "" " -cvalidate"

It declares to use a .xbb file for determining the image dimensions
when image is included without dimension hint (ie.
\includegraphics{plot}). In your example, where you use explicit
dimensions it is not so important, but I think it is useful in
general.

The .xbb file can be created using

    ebb -x image

command. Note that not every image format is supported.
