Embedded dot not compiling>

Embedded dot not compiling>

[Peter Davis]

I've been using org-mode for a while, in some cases with embedded dot code. This has worked pretty smoothly for me in the past, but
for some reason, I'm not getting any png output from my graphs now. The doc I'm started is included below, in its entirety since
it's still pretty small.

Anything jump out? I don't see any errors, but the png file is not created.

Thanks!

Should you have "node" on each node line?  I thought nodes were simply
lines with no keyword?

By the way, newish versions of org actually report back any error
message from the babel block.  In this case, org tells me:

Error: /tmp/babel-4890lUw/dot-48901c0: syntax error in line 3 near '['

i.e. the first node line.

Thanks. I'm running 8.3.3, and didn't see any error messages.
