Design can also aid in selling a product or idea through effective visual communication. Before any graphic elements may be applied to a design, the graphic elements must be originated by means of visual art skills. Visual arts include works which are primarily visual in nature using anything from traditional media, to photography or digital art. Graphic design principles may be applied to each graphic art element individually as well as to the final composition. Graphic design combine art and technology to develop graphics for product illustrations, logos, and websites.
