Thanks, John. Just running pdflatex from the command line gives me:
! Undefined control sequence.
l.36 \tikz
[remember picture]\node[coordinate,yshift=0.5em] (n1) {};
So perhaps TikZ itself is not available to some part of this.
Thanks,

That implies you have not configured org-mode to include the tikz
package.
If you execute this block in a buffer does it work?

I always go back to straight LaTeX to debug such problems:

I do have:
(add-to-list 'org-latex-packages-alist
'(("AUTO" "inputenc" t)
("" "color" t)
("" "minted" t)
("" "parskip" t)
("" "tikz" t)))
Any other setup work I need?

Yes, but have you executed that? What does C-h v org-latex-pacakges-alist RET say?

org-latex-packages-alist is a variable defined in ‘org.el’.
Its value is (("" "tikz")
("" "listingsutf8")
(("AUTO" "inputenc" t)
("" "color" t)
("" "minted" t)
("" "parskip" t)
("" "tikz" t)))

This looks wrong. You're adding a single list to org-latex-package-alist, instead of adding multiple elements one-by-one.

Ok, I tried changing it to:
(add-to-list 'org-latex-packages-alist '("AUTO" "inputenc" t))
(add-to-list 'org-latex-packages-alist '("" "color" t))
(add-to-list 'org-latex-packages-alist '("" "minted" t))
(add-to-list 'org-latex-packages-alist '("" "parskip" t))
(add-to-list 'org-latex-packages-alist '("" "tikz"))
(add-to-list 'org-latex-packages-alist '("" "listingsutf8"))
so now org-latex-packages-alist has the value
(("" "listingsutf8")
("" "tikz")
("" "parskip" t)
("" "minted" t)
("" "color" t)
("AUTO" "inputenc" t))
Still getting the failure on tikz output.
Thanks!

Maybe I'm dense, but why is everyone recommending changing the alist?
Granted, for future proofing and convenience this is nice... but I do
a fair amount with TikZ and have never done this.
~/org/aux/setupfile.org contains:
#+latex_header: \usepackage{tikz}
#+latex_header: \usepackage[siunitx]{circuitikz}
#+latex_header: \usetikzlibrary{shapes, positioning}
any given .org file contains:
#+setupfile: "~/org/aux/setupfile.org"
I modified your original aim like so, ditching the .png output which
looks like requires imagemagick. Maybe that's in org somehow, but when
you're just starting out I'd suggest eliminating as many other
mechanisms as possible. TikZ is in LaTeX, so just stick to pdf at the
start. This works for me.
#+latex_header: \usepackage{tikz}
#+latex_header: \usetikzlibrary{shapes, positioning}
* test
#+begin_src latex :results raw
% Define block styles
\usetikzlibrary{shapes,arrows}
\tikzstyle{astate} = [circle, draw, text centered, font=\footnotesize,
fill=blue!25]
\tikzstyle{rstate} = [circle, draw, text centered, font=\footnotesize,
fill=red!25]
\begin{tikzpicture}[->,>=stealth', shorten >=1pt, auto, node
distance=2.8cm, semithick]
\node [astate] (1) at (0,0) {1};
\node [astate] (2) at (1,0) {2};
\node [rstate] (3) at (2,0) {3};
\path (1) edge [bend left] node {b} (2)
(2) edge node {b} (3)
(2) edge [bend left] node {a} (1)
(3) edge [loop above] node {(a, b)} (3);
\end{tikzpicture}
#+end_src

Ok, my problem was that the minted package was causing errors. Taking
that out lets me generate pdf.
Now to figure out how to generate other formats, to work with HTML and
LaTeX/PDF output.
Thanks, all!!

That is probably because with minted you have to modify how the pdf is
built to use pdflatex -shell-escape.
The variable org-latex-pdf-process controls this.

Maybe a distraction from the discussion on graphing alternatives that
can be embedded into the org/LaTeX code but I am pretty happy with the
results I get from using Veusz.
http://home.gna.org/veusz/
Adding to the confusion by adding a recommendation for a program I use
to create numerical data from graphs:

Hi,
I'm using the following header, which lets me export to PDF and HTML,
both (basically from here:
http://orgmode.org/worg/org-contrib/babel/languages/ob-doc-LaTeX.html).
#+header: :exports results :file fsa.png
#+header: :imagemagick yes :iminoptions -density 600 :imoutoptions
-geometry 1200
#+header: :fit yes :noweb yes :headers '("\\usepackage{tikz}")
#+begin_src latex :exports results :results raw :file fsa.png
(and no #+Results line, but I don't know if this matters)
Also, regarding the babel I use the following to map source blocks to
"supported" LaTeX listings languages:
Add “text” and “conf” to =latex-listings-langs= with empty (space as a
trick) language name to be used in the LaTeX listings package.
#+begin_src emacs-lisp
(add-to-list 'org-latex-listings-langs
'(text " "))
(add-to-list 'org-latex-listings-langs
'(conf " "))
(add-to-list 'org-latex-listings-langs
'(nxml "XML"))
(add-to-list 'org-latex-listings-langs
'(org " "))
Best regards
