#+LATEX_HEADER: \usepackage{tikz}

What does the above line do exactly?
This will ensure, that the produced latex file for the diagram loads
tikz. I could not find that documented, so maybe that should be
replaced by ':headers '(\\usepackage{tikz})'. In my first tests it
now seems unnecessary, maybe due to a change in the semantics of
LATEX_HEADER when LATEX_HEADER_EXTRA was introduced.
So, I guess you can omit that altogether.
#+header: :file (by-backend (latex example_diagram.tikz) (html
example_diagram.svg) (t example_diagram.png))
The manual says that after :file I can have a string or a list of two
strings. Does the above mean that it is in fact macroexpanded?
The argument of any header option can be replaced by an elisp form
(which then in this case should return a string or a list of two
strings).
Do
I get it correctly that the (t example_diagram.png) refers to manual
evaluation and not the evaluation during the export?
Yes. I use that to be able to see the diagram within the org document.

And, last but not least: how exactly the magic of tikz - svg is
supposed to work here? Do I get it correctly that in you example,
Imagemagick handles both png and svg?
Yes, imagemagick does both here. And there is a bug in imagemagick up
to 6.9 producing corrupt svg [1]. I guess that is hitting you. Try
upgrading your imagemagick.
What if I want to use pdf2svg
instead?
I do not think that this is possible right now.
BUT:
You can use htlatex.
If you look at worg [2], you'll find an example demonstrating that.
It mainly requires setting
'(setq org-babel-latex-htlatex htlatex)'.
I think that possibility might make pdf2svg unnecessary.
BUT 2:
This won't have an effect on the example in this thread.
I consider it a bug that the example I gave in this thread tries to run
imagemagick for the svg even if that variable is set to htlatex. I'll
file a bug report in a separate thread.

I had forgotten about that thread. Very useful, in particular finding
an example that uses gnuplot to generate tikz output. However, in
trying a simple example:
#+begin_src org
* gnuplot
#+latex_header: \usepackage{gnuplot-lua-tikz}

[[file:tikzgnuplot.tikz]]
#+end_src
I found that the ~latex_header~ line was necessary as the tikz generated by
gnuplot requires that package.
I'm putting this here as a /heads up/ for anybody else trying this.

The example I posted earlier in this thread [1] uses the *.tikz version for
latex export.
I do not know, whether that helps, but I think the behaviour of the tikz
graphics has been decided in this thread [2].
The wrapping in tikzpicture if options are present is quite sensible, as
these options have to be presented somewhere. Note, that it is fine to
nest tikzpicture environments. So, the *.tikz file is basically
expected to bring its own tikzpicture environment. If there are options
given in the org file, this is just wrapped into another tikzpicture
environment. (If I understand the reasoning correctly, that is...)

Andreas

What'd be nice is that you could say (in a *file* property) that the

all the other cases.
I agree. Especially if that setup should be applied to every figure in
the document, the header repetitions are tedious. I do not have a
solution, I am afraid.
Then, you could simply give the base name of the figure where
appropriate, in a DRY configuration.
I'd love to see that, too.

the PDF file -, and the ellipse in the middle of the sentence appeared,
but the block

#+end_src
did not make its way to the t.tex file... I asked for help in the
#org-mode channel at freenode, as I am an Org newbie, and found a fix.
Your example is one of the best one I've seen so far of diagrams-
in-Org-for-newbies, but it seems to be at least one micro-bug from
perfect, as it supposes that the person trying it has already enabled
latex support in babel!
Here is an idea to make your example more newbie-friendly: add the
comments below to it.
# Note that you may have to add latex support to babel
# to make the tikzpicture block work...
# see: (info (org)Languages)
# try: (org-babel-do-load-languages 'org-babel-load-languages '((latex . t)))

# To disable to question Evaluate this latex code block on your system?,
