Well, there are indeed examples in there, but not in Data.GraphViz:
that module is aimed more at "how can I convert my existing data into
a Dot representation", not constructing one by hand. As of the latest
version (2999.12.*), there are indeed examples for anyone that wants
* Sample graph in Dot representation used as a base case:
* Using the canonical representation:
* Using the graph representation:
* Using the Monadic representation (based upon the dotgen package):
The Data.GraphViz.Types module also has a short description of how to
choose which representation.
However, I'll add a note in Data.GraphViz telling people to look in
Data.GraphViz.Types if they want to construct a Dot graph by hand.

I'd say it's more a case of: to the maintainer, it's _obvious_ how to
do stuff since they're intimately familiar with the details; as such,
if something isn't clear let them know that you're confused by
something (which at least in my case jogs me to go and add extra
clarification on such matters)!
