@cbaenziger had to tweak your PR a little. Does this look OK to you?

Thanks! LGTM and works on my test with hugo serve. BTW should I add the dot command to the build.sh?

BTW should I add the dot command to the build.sh

Oh, that's not a bad idea (if the command exists). Let me try to add that.

Let me try to add that.

Not super feasible because it will clobber the ASF license header. I don't see an obvious way to re-add the license via the DOT file itself, so I'm just skipping that part.

But, there is some good improvements coming into build.sh as a result of me messing around here.

[joshelser]

Can you take a look again, @cbaenziger ?

[cbaenziger]

Looks good but you may want one more set of double quotes.

[joshelser]

OK, 261e8a1 can regenerate the license header on OSX. Let me test on Linux too.

[joshelser]

15ca39f fixes the issue of building on Linux. Going to squash/rebase this one as I think this will be good for what you were looking for :)

If the user doesn't have dot on the $PATH, we won't re-generate the SVG and everything else should continue as expected.

[joshelser]

Merged!

oh great!! I didn't know that a framework like Graphviz exists. Visualization looks great. Thanks for working on this.
