Sure, by the time you enter all the specifics of the Circle, you've got something more unwieldy than a succinct programmatic description.

But for most people unfamiliar with Mathematica syntax, typing, "draw a red circle" and having the computer choose sensible (or any) defaults yields a template of the exact code one would have needed to type. Which saves Googling or reading the manual for circles, and teaches the syntax in a very natural way.

That is correct...it is nice to be able to see the underlying Mathematica code that any natural language query generates. Here's your "draw a red circle" example:
