A software program can be represented as a map depicting respective software components of the software program. A grid system can be used, and map elements can be contiguous geometric shapes. Affinity between the software components can be represented in the map, such as by placing corresponding map elements close to one other in the map. During navigation through source code, an indication of where within the source code the navigation has occurred can be displayed on the map. Paths can be shown on the map. A technique for building the map can rely on a metric of a software component when generating a corresponding map element in the software map. The map can be depicted as a geographic map to help developers locate components.
