I demoed it so often that I almost forgot blogging about it: In Xtext 2.0 you can now visualize the syntax of your DSLs grammar in a live railroad diagram view. The view supports navigation between the editor and the view and you can export your diagrams to a file. We even have a special representation for unordered groups. Watch this screencast to see it in action:
The syntax graph is implemented in plain Draw2d using a custom layout algorithm. It is technically not related to the generic graphical view I presented in my previous blogpost.

Nice, but I think you'd usually end up using the equivalent visualization from ANTLRWorks anyway, because that allows you to analyze ambiguities.
@Meinte AnltWorks opearates on a different level of abstraction (the generated Antlr grammar) than the Xtext syntax view. Furthermore, it is not integrated into Eclipse and synchronizes with the grammar editor. It's just a question of time until ambiguity analysis will be added to the grammar editor and integrated into the view.
It is open source?
Sure, it's part of Xtext 2.0 and higher.
