Re: [O] Best diagram, image software?

[Peter Davis]

Since several people recommended TikZ, I decided to take a look at it.
It seems very powerful, but I'm unable to get any example to work. For
example, using the example here: 

http://doblogit.com/posts/2015-10-23-org-graphics.html

#+begin_src latex :exports results :results output raw :file
images/fsa.png
% 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


I get:

org-babel-exp process latex at line 6...
executing Latex code block...
org-latex-compile: PDF file
c:/Users/pdavis/AppData/Local/Temp/orgtex5448hGP.pdf wasn’t produced

I've got ImageMagick installed. I don't know how to debug this.
