Continuing from #9 . For multi-edge graphs, the set of edges and the set of connected vertex pairs are not the same. For example, in the SDP relaxation of OPF, one may want to analyze entries of the PSD matrix variable, which is by definition on the bus pairs, not on the branches. Currently viz_opf only supports variables on branches, so it will need to support variables on bus pairs.
