Thanks for checking. some update: using your new driver

Now the HTML shows the tikz shapes. But all the text is missing.
i.e. for this MWE

---------------------------
\documentclass[12pt]{article}
\ifdefined\HCode
   \def\pgfsysdriver{pgfsys-tex4ht-updated.def}
\fi
\usepackage{amsmath}
\usepackage{tikz}

\begin{document}

\begin{tikzpicture}
\node at (0,0) [circle, fill=yellow, inner sep=1pt] { some text};
\end{tikzpicture}

after tikz
\end{document}
-------------------------------

Compiled using

make4ht --shell-escape -ulm default -a debug foo3.tex 'mathjax,htm'

The generated html shows now the yellow circle. But "some text" is missing.

Ofcourse the pdf show the text in the tikz picture.

I tried with htm and without and tried with mathjax and without.
All math and text are missing from the tikzpicture in the .svg file generated.

>which make4ht
/usr/local/texlive/2023/bin/x86_64-linux/make4ht
>make4ht --version
make4ht version v0.3m

I've put a new zip file that includes all the above MWE with
all files generated in this folder

https://12000.org/tmp/oct_23_2023/

The zip file is

    tikz_problem_with_tex4ht_v2.zip

So some progress is made by using make4ht updated driver. But the
question now is why no labels and no text show up for me.

But if all else fails, I can generate images for the tikzpics
and includes this as graphics for HTML.

Thanks
