Movie S1
Experimental differential conductance, g(Vb, Vg, r, B) maps of the local density of states of the graphene QD in the x-y plane as a function of sample bias, Vb, indicated in the top center of the movie. The movie has four quadrants showing four different magnetic fields, 0, 1, 2, and 3 T. Various QD states are seen coming in at different bias, corresponding to the states observed in Fig. 2 of the main text. A smooth background was subtracted from each dI/dV spectra to remove the graphene dispersion in order to visualize all features on a single color scale.
