Hi Márton, 

Thanks for your answer. But now I'm even more confused as it somehow
conflicts with the documentation. ;)
According to the wiki and the stratosphere paper the JobGraph will be
submitted to the JobManager. And the JobManager will then translate it into
the ExecutionGraph.

So the ExecutionGraph should only be available at the JobManager and contain
a node for each parallel instance of a operator and the corresponding
vertices.

The question is in the context of my master thesis as I'm trying to describe
the deployment process of Flink. And wan't to use a visualization of the
execution plan as an concrete example for one of these three Graphs.

Best Alex!
