#'A data containing 3 variables(v1,v2 and w) which contains the edges of the
#'graph (from v1 to v2) with the weight of the edge (w).
#'v1 = c(1, 1, 1, 2, 2, 2, 3, 3, 3, 3, 4, 4, 4, 5, 5, 6, 6, 6),
#'v2 = c(2, 3, 6, 1, 3, 4, 1, 2, 4, 6, 2, 3, 5, 4, 6, 1, 3, 5),
#'w = c(7, 9, 14, 7, 10, 15, 9, 10, 11, 2, 15, 11, 6, 6, 9, 14, 2, 9)
