The present work provides an overview of visualization methods for linear-response TD-DFT, going beyond molecular orbitals (MOs) and aiming to describe (and potentially quantify) how charge is rearranged upon electronic excitation. Both density-based and orbital-based visualization tools are considered, as are certain atomic partitions of the density change upon excitation, ∆ρ(r) = ρ exc (r) -ρ 0 (r) .
