Final answer:
A graphic that is recognized by the audience without explanation is considered part of the audience's visual vocabulary.
Step-by-step explanation:
When a graphic, like a symbol on a website's navigation bar, is repeated so many times that the audience recognizes that graphic's meaning without instruction or explanation, that graphic is considered part of the audience's visual vocabulary. Graphic designers use symbols, such as logos, to convey meaning in a visually impactful way. When these symbols become familiar to the audience, they become part of their visual vocabulary.
