  create_graph(
    directed = FALSE) %>%
  add_gnp_graph(
    n = 100,
    p = 0.05
  )

# Save the graph to disk; use
# the file name `gnp_graph.dgr`
# save_graph(
#   x = gnp_graph,
#   file = "gnp_graph"
# )

# To read the graph file from
# disk, use `open_graph()`
# gnp_graph_2 <-
#   open_graph(
