anchor.diff:  you would then need to iterate through `x`. This understanding is *important* because in the context of the console
   typing `g.V()` instantly returns a value. The console does some magic for you by noticing that `g.V()` returns
   an `Iterator` and then automatically iterates the results. In short, when writing Gremlin outside of the console
  -always remember that you must iterate your `Traversal` manually in some way for it to do anything.

  +"iterating your traversal" is described further in link:http://tinkerpop.apache.org/docs/x.y.z/tutorials/the-gremlin-console/[The Gremlin Console Tutorial].
   
   In this first five minutes with Gremlin, you've gotten the Gremlin Console installed, instantiated a `Graph` and
   `TraversalSource`, wrote some traversals and hopefully learned something about TinkerPop in general. You've only
   scratched the surface of what there is to know, but those accomplishments will help enable your understanding of the

   The Next Fifteen Minutes

positive.code: 
  The use of `by()` here provides the mechanism by which to do the grouping. In this case, we've asked Gremlin to
  use the `label` (which, again, is an automatic static import from `T` in the console). We can't really tell much
  about our distribution though because we just have vertex unique identifiers as output. To make that nicer we
  could ask Gremlin to get us the value of the "name" property from those vertices, by supplying another `by()`
  modulator to `group()` to transform the values.
  
  
negative.code: embedded link:http://tinkerpop.apache.org/docs/x.y.z/reference/#_developing_a_driver[subprotocol] that allow a
  compliant driver to communicate with it.  TinkerPop supplies a
  link:http://tinkerpop.apache.org/docs/x.y.z/reference/#_connecting_via_java[reference driver] written in Java, but
  there are drivers developed by both TinkerPop and third-parties for other link:http://tinkerpop.apache.org/#graph-libraries[languages]
  such as Python, Javascript, etc. Gremlin Server therefore represents the method by which non-JVM languages can
  interact with TinkerPop.
