I too got confused assuming the list to represent all examples of poor visualisation. Reading the text didn't help much. Because the list is presented top-down in sequence, a reader immediately assumes a homogeneous list of items. A side-by-side would make clear distinction of "Good" vs "Bad". I agree with jmpeax. This page needs to be presented as an example of poor presentation.
