### Arguments

### Value

a vector of node ID values.

### Examples

    # Create a graph and add 4 nodes
    # in 2 separate function calls
    graph <-
      create_graph() %>%
      add_n_nodes(
        n = 2,
        type = "a",
        label = c("a_1", "a_2")) %>%
      add_n_nodes(
        n = 2,
        type = "b",
        label = c("b_1", "b_2"))

    # Get the last nodes created (2 nodes
    # from the last function call)
    graph %>%
      get_last_nodes_created()
    #> [1] 3 4
