""text based"
If this an absolute, then LV can not be used!
I used to be able to read machine code which was a bunch of octal values repested by groups of lights. It was readable to me and I was human back then.
If I had a utility that translated it into hebrew which is human readable would that be OK? What about braile?
When you drive down a road and see a pictogram sign that tells you winding road, you as a human can read it but it is not text.
In my book (for what little that matters) a LV diagram is much more readable than any code written in any other language I have ever seen.
This idea that computers programs MUST go through some sort of text phase is ancient history.
