A graph consists of nodes and edges. An edge is an (unordered) pair of two distinct nodes in the graph. We create a new empty graph from the class Graph. We use the add_node method to add a single node and the add_nodes method to add multiple nodes. Nodes are identified by unique symbols. We call add_edge with two nodes to add an edge between a pair of nodes belonging to the graph. We can also ask a graph for...
