Graph is directed

WebNote: We've chosen a weighted directed graph as the example because it illustrates most of the implementation nuances. Generally speaking, switching between weighted and unweighted graphs is pretty straight-forward. Switching between directed and undirected graphs is also a pretty easy thing to do. We'll cover each of those topics in the ... WebFeb 16, 2024 · Example 2: small directed graph with loops and multi-edges. In this example, we’ll keep our nodes data frame from above, but specify a new data frame of edges. Since we want loops, we’ll have a relationship going from 2 to 3 and from 3 to 2, giving us a loop. The second sort of loop we’ll create is a self-edge, where a relationship …

Non-directed / bidirectional graphs have edges where you can go back and forth between vertices. Cyclic graphs are graphs with cycles. Basically, there is at least one path in the graph where a vertex can come back to itself.
