Thank you @MeltemTolunay . I am noticing there is no 'prerequisite' section -- could you add appropriate material (or flag to me if there are none).

I am also noticing we import qiskit-device-benchmarking, for purpose of using the plot_gate_map function. Is it not possible to instead use the same qiskit visualization function?

please also be sure to include steps for small simulator example. Otherwise, I think this looks good! (Thank you!)
