so, the translated visual basic thing is a thing i remember hearing about vba in the 90s, without any personal experience. but if memory serves (and i'm not just confabulating the whole thing) it was built-in, not an add-on
i think it's reasonable to describe graphical notations such as drakon as having a grammar. you have some finite set of atomic features (often things like shapes or arrows, but sometimes other characteristics such as size, orientation, and color) which are combined in some finite set of ways to produce an infinite set of possible 'sentences'. the only non-grammatical aspect of this is that some of these features are used in an analog way, for example with a length proportional to a time lapse or an orientation that indicates a cardinal direction, while verbal features are strictly digital and arbitrary—but we often use similar paralinguistic features in speech and especially in sign language
