Hi Ken, I think this would be an interesting feature! I'd suggest to open a JIRA for it.
When extending the API of core classes such as ExecutionEnvironment, there is often some discussion whether the feature is important enough or whether it should be rather added to some external util class (which makes it obviously less visible). I think this feature would be valuable enough to be added directly into the ExecutionEnvironment. DOT is a common format for graph and flow visualizations. Let's see what others think.
