It depends on how you use the term "visual programming language", which unfortunately has a lot of baggage around it. It is not sticking lego blocks together like Scratch or LEGO Mindstorms, nor is it the boxes with arrows pointing at eachother like Max MSP/Lab View/Blueprint/noflo, but it's also not strictly textual. The closest analog really is Excel or Access, but with the ability to describe how you translate one sheet/table to another one. Your main interface is a grid of data and a list of output tables. On top of that sits a set of domain editors though, to make drawing UI, for example, not an exercise in writing a bunch of rows out into a table. Instead you use a photoshop-like tool to just draw your UI. Same with doing math or string operations or flying drones or working with music and so on. We of course can't cover every domain, but what's interesting is that the editor is itself kind of like an editor of editors and it'll make it fairly trivial for you to build your own manipulable representations.
