As somebody who spent some time working with LabVIEW, I can safely say that drawing a circuit diagram is more difficult and less intuitive than using text. Now, maybe this is the fault of LabVIEW, but I think it's true in the general case as well.

I once had to use LabVIEW. In general, I agree with you, but I got the feeling that G (the language implemented in LabVIEW) might almost be a decent language if the only IDE for it (and the file format) didn't suck so badly.
