visualGraph(G)

function visualGraph(G)
% This function allows to visualize the evolution of a temporal graph. The
% layout is a ring lattice.
% Inputs:
% - G: the temporal graph under form of a 3D-matrix in which the 1st and
% 2nd dimension denotes the node's IDs and the 3rd dimension denotes the
% time.
