I don't understand why Squeak or Self (with or without Morphic) would be considered visual programming languages. Don't get me wrong, I think Morphic is a pretty slick system, but still... Perhaps because it was not made quite clear what is considered to be a "visual programming language". Based on what is in this list, though, it would seem to me that e.g. the combination of "Objective-C and InterfaceBuilder" could also be added to the list, which feels silly.
