WebFeb 18, 2024 · An edge in the graph is defined as a tuple containing the origin and target node, so for example the edge (2, 3) connects node 2 to node 3. Since we have a directed graph, there can also be an edge (3, 2) which points in the opposite direction. Multiple edges can be added to the graph as part of a list in a similar manner as nodes can:
