An information graphics can basically include verbal information. Many infographics done by an infographic company like maps have keys which are designed to explain all of the elements of the graphic, making it easier to understand. Others, such as subway maps, use words to designate each station, as well as bright colors illustrating the different routes. When charts are used to present data, they also typically have verbal information; the side of a bar graph, for example, might explain that one axis showed the number of people with cars, while the other side indicated which country the car owners lived in.
Visual presentation of information is a powerful tool. Sometimes a complex concept can be more quickly understood with the use of infographics than through words. The universal comprehension factor is also very valuable in a mixed group, and the use of infographics ensures that information will be accessible to people thousands of years in the future, who may not understand the system of written communication used; for example, nuclear waste disposal sites use infographics to explain that they are dangerous.
