Pictographs are designs painted on a rock surface which convey meaning through their pictorial resemblance to physical objects. Earliest examples of pictographs include ancient or prehistoric drawings or paintings found on rock walls. Pictographs are also used in writing and graphic systems in which the characters are pictorial in appearance.
