Using scanning tunneling microscopy, we have imaged local charge densityfluctuations in monolayer graphene. By placing a small gold nanoparticle on theend of the STM tip, a charge sensor is created. By raster scanning the tip overthe surface and using Coulomb blockade spectroscopy, we map the local charge onthe graphene. We observe a series of electron and hole doped puddles with acharacteristic length scale of about 20 nm. Theoretical calculations for thecorrelation length of the puddles based on the number of impurities are inagreement with our measurements.
