  We present a method for bridging the gap between the Dirac effective field
theory and atomistic simulations in graphene based on the Husimi projection,
allowing us to depict phenomena in graphene at arbitrary scales. This technique
takes the atomistic wavefunction as an input, and produces semiclassical
pictures of quasiparticles in the two Dirac valleys. We use the Husimi tech-
nique to produce maps of the scattering behavior of boundaries, giving insight
into the properties of wavefunctions at energies both close to and far from the
Dirac point. Boundary conditions play a significant role to the rise of Fano
resonances, which we examine using the Husimi map to deepen our understanding
of bond currents near resonance.
