Which for me begs the question, is LabView worth it? It's the only widely used Visual Programming Language I can think of.

Every time someone posts a visual programming language prototype the same claims are made over and over again. Like; adds too much complexity, throws out benefits of text editing, eats up too much screen space etc etc.

I'm convinced that many of those issues can be overcome and that until we figure out how to overcome them I'd like to understand which niches Visual programming really makes sense until then.

If LabView makes sense and is worth it, there ought to be more applications where it makes sense!
