    # Create an undirected GNP
    # graph with 100 nodes using
    # a probability value of 0.05
    gnp_graph <-
      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(
        file = "gnp_graph.dgr")
