[O] Auto-refreshing rendered images from org-babel

[E Sabof]

I have the org snippet below. What I would like, is to see the rendered image 
when I press C-c C-c. I can achieve this with the elisp snippet below. Is there 
a "proper", or at least a better way of doing this?

#+BEGIN_SRC dot :file files/graphviz/example1.png
digraph test {
    size="6,5";
    home [label = "Home"];
    prod [label = "Products"];
    news [label = "News"];
    cont [label = "Contact"];

    home -> {prod news cont}
}
#+END_SRC
