A simple map is a map that only shows essential information like major streets, landmarks, routes, or borders. Simple maps provide necessary information in an easy-to-read format, so you can find exactly what you're looking for at a glance. Looking for a map of San Francisco's main highlights? A simple map of downtown San Francisco would only show highways to guide you into the city, the main roads to get you around the city, and important landmarks like the Golden Gate Bridge. Simple maps can be made for specific purposes such as visualizing simple data, providing directions, or showing locations of a particular business. Other kinds of maps could be too cluttered for this purpose, offering excess information that detracts from the map's purpose.
A simple map can be an outline map, street map, blank map, or even a political map. Political maps don't have anything to do with democrats and republicans, like some might think. Political maps show state, country, and territory boundaries, and often include the capital and major cities. The name “political” refers to political boundaries rather than politicians. Since political maps are clutter-free, they can be considered simple maps too.
