  We present a mathematically simple procedure for explaining and visualizing
the dynamics of quantized transport in topological insulators. The procedure
serves to illustrate and clarify the dynamics of topological transport in
general, but for the sake of concreteness, it is phrased here in terms of
electron transport in a charge-ordered chain, which may be mapped exactly onto
transport between edge channels in the Integer Quantum Hall Effect. It has the
advantage that it allows a direct visualization of the real-space and real-time
evolution of the electronic charges throughout the topological pumping cycle,
thus demystifying how charge flows between remote edges separated by an
insulating bulk, why the amount of transported charge is given by a topological
invariant, and how continuous driving yields a discrete, quantized amount of
transported charge.
