For one thing I don't understand 90% of the options, that can explain a lot.
Another point, the gibberish output I was speaking about are "similar" those
of
[[https://emacs.stackexchange.com/questions/68823/minimal-working-example-of-tikz-to-svg-in-orgmode]]
Actually the svg image they get is an image containing the `tikz` instructions
transformed as image. What I get is the svg instructions that should generate
the image: an image showing a `svg` listing.
Anyway
You start from that:
#+begin_src emacs-lisp
(setq org-latex-compiler "lualatex")
#+end_src
#+name: circle
#+header: :results file drawer
#+header: :file circle.svg
#+header: :dvisvgm yes
#+header: :headers '("\\usepackage{tikz}")
#+begin_src latex
\begin{tikzpicture}
\fill[yellow] (0,0) circle (3cm);
\end{tikzpicture}
#+end_src
You do C-c C-c on both blocks.
Looking at *Messages* you see there is a file
```
cat /tmp/babel-DQ59bY/latex-2whyWA.tex
\documentclass[preview]{standalone}
\def\pgfsysdriver{pgfsys-tex4ht.def}
\usepackage{tikz}\begin{document}\begin{tikzpicture}
\fill[yellow] (0,0) circle (3cm);
\end{tikzpicture}\end{document}
```
Among `latex`, `pdflatex`, `lualatex`, `htlatex`, the latex file can only be
successfully processed by `htlatex`, which will produces several outputs:
```
ls *2whyWA*
latex-2whyWA-1.svg latex-2whyWA.4tc latex-2whyWA.css latex-2whyWA.html
latex-2whyWA.lg latex-2whyWA.tmp
latex-2whyWA.4ct latex-2whyWA.aux latex-2whyWA.dvi latex-2whyWA.idv
latex-2whyWA.log latex-2whyWA.xref
```
One of them is `svg` file and is correct.
I've tried replacing `(setq org-latex-compiler "lualatex")` by every possible
latex compiler listed above.
I've also tried replacing `#+header: :dvisvgm yes` by `htlatex` and
`inkscape`.
In every case I get the gibberish output, specifically an image of the listing
of the svg output, or in any case something resembling to `XML`.
Something else I can do "by hand":
```
lualatex -jobname=foo <(sed '/pgfsysdriver/d' /tmp/babel-DQ59bY/
latex-2whyWA.tex); dvisvgm --pdf --output=foo.svg foo.pdf
```
then:
```
$ cat foo.svg
<?xml version='1.0' encoding='UTF-8'?>

I got that last trick from [[https://en.wikipedia.org/wiki/
Wikipedia:Graphics_Lab/Resources/PDF_conversion_to_SVG]]
We can see both files have the exact same size, `foo.svg` is 548 bytes,
`latex-2whyWA-1.svg` is 855 bytes.
`foo.svg` is superior in that it uses `utf-8` encoding, which is superior.
bitmaps outputs for `tikz` are not nice.
So two ways to do it by hand, and it would be nice to have it doing it
automatically.
Wikipedia says `inkscape` method can yield heavy results, and indeed I had to
install `potrace`.
They say in the stackexchange page that `pdflatex+inkscape` is the default
method, so even it didn't work at all, I followed the instruction it gave me
to first install `inkscape` and then install `potrace`.
What I like best is:
```
lualatex -jobname=foo <(sed '/pgfsysdriver/d' /tmp/babel-DQ59bY/
latex-2whyWA.tex); dvisvgm --pdf --output=foo.svg foo.pdf
```
It would be easier if second line `\def\pgfsysdriver{pgfsys-tex4ht.def}` was
not inserted in the first place.
I think the way plain `org-latex-preview`, which work for me, are generated is
through `latex + dvisvgm` and I think that in this case the above
`\def\pgfsysdriver{pgfsys-tex4ht.def}` isn't used neither.
Using "old" `latex` can be troublesome in some cases though, namely everytime
somebody is trying to use some `utf-8`.
Best,
Chris
