Is it typography?
The best definition of typography comes from Type and Typography by Phil Baines & Andrew Haslam.
Typography: The mechanical notation and arrangement of language.
As something of a contrast, this recently caught my eye—the lyrics from a CD by pop singer Kesha. The pages demonstrate both organization and hierarchy, so for me this is typography too, even if it doesn’t meet the strict definition above. Maybe not great typography, but typography just the same.
