This chapter provides an overview of the key terms, concepts, and some design principles for the modern forms of mapping. The purpose of animation is to draw attention to a component of the map or communicate thematic data. Flipbooks function similarly to a cartoon or film, with a rapid succession of static maps to produce the illusion of movement and dynamic change. A pointer highlights some portion of the map by adding lines, illuminating a part of the layout, or adding notation to the map. Animations can improve cartographic comprehension by making data complexity more easily navigable or digestible for readers, and can include feedback mechanisms to help users locate information more quickly. The idea of imposing left- and right-eye perspectives onto a single plane in separable visual channels was later accomplished using polarized light. The rise of web and mobile cartography has given birth to a host of new terms in cartography.
