The coherent flow of electrons through a graphene device is an intriguing physical problem, which must be understood for future quantum technologies. We have developed a low-temperature scanning probe technique for mapping the effect of a single movable scatterer on coherent transport in graphene. We obtain images of conductance vs. scatterer position that provide a spatial view of the interference of electron waves that create universal conductance fluctuations and weak localization.
