I like the style of that tube map, but despite not being able to do math or tell time well, I’m a physically spatial person and am more comfortable knowing/seeing/feeling distances, directions and where things actually are. So as I use a system I end up trying to make something more like the second “realistic” map somewhere eventually.
Re this:
His map looks exactly like a technical draft. Looks like circuit schematics. It sounds like they mean “Henry was never trained in art.” Draftsmen design, in my view.
