The art and practice of planning and projecting ideas and experiences with visual and textual content is graphic design, also known as communication design. The form it takes may be physical or virtual, with images, words, or graphics included. The experience can occur in an instant or for a long time. The work can be done on any scale, from designing a single postmark to a national postal signage system. It can be designed for a small number of people, such as a one - off or limited - edition book or exhibition design, or can be viewed by millions, as with an international news organization's interlinked digital and physical content. It can also be commercial, educational, cultural, or political for any purpose.
