% tiny_01.graph
% A very small example of an unweighted graph
% stored in the METIS graph file format.
%
% The first non-comment line lists
% the number of vertices (7) and edges (11).
%
% The next line notes that vertex 1 is connected to vertices 5, 3 and 2.
% Subsequent lines list the neighbors of successive vertices.
%
% Notice that each edge is listed twice. There are 11 edges,
% but 22 edge entries.
