Logos are a specific type of graphic design symbol used to represent a company's identity. Iconography is the use of images and symbols in artwork and the study of their meaning.
Step-by-step explanation:
Images created to inform as well as embellish the printed page are known as illustrations. These are an integral part of visual communication in various forms of media and serve to complement and elaborate on the text they accompany. An illustration could be found in an ancient manuscript, a modern book, or even as part of advertisement materials, aimed at both informing and enhancing the visual appeal.
Graphic designers often create logos, which are symbols representing the corporate identity of a company. The design of a logo has to be unique, easily identifiable, and reflect the character of the brand.
Furthermore, iconography plays a significant role in the arts, as it involves the visual images and symbols used in a work. This term also refers to the study or interpretation of these images and symbols within the context of art history.
