us which vertices in the original graph made
% it into the largest strong component.  We can just apply that filter to
% the coordinates xy and reuse them for drawing the graph!

%% Statistics
% Graph statistics are just measures that indicate a property of the graph
% at every vertex, or at every edges.  Arguably the simplest graph
% statistic would be the average vertex degree.  Because such statistics
% are easy to compute with the adjaceny matrix in Matlab, they do not have
% special functions in gaimc.
