This function and all of its descriptions have been obtained from the igraph package.

`graph_from_data_frame(d, directed = TRUE, vertices = NULL)`

- d
A data frame containing a symbolic edge list in the first two columns. Additional columns are considered as edge attributes. Since version 0.7 this argument is coerced to a data frame with as.data.frame.

- directed
Logical scalar, whether or not to create a directed graph.

- vertices
A data frame with vertex metadata, or NULL. Since version 0.7 of igraph this argument is coerced to a data frame with as.data.frame, if not NULL.

An igraph graph object.
