Edge Files

Edge files are text files that contain the edges of a directed graph, one per line. The syntax is:

Source_Node -> Sink_Node.

The source node is the point from which the edge emanates, and the sink node is the point at which the edge terminates. The strings denoting the nodes can contain any characters except "->". Any whitespace around the arrow is ignored. Self-loops are allowed, but duplicate edges, that is, multigraphs, are not.

See the Text Formatting Rules for additional information.
