// Create an empty graph of strings
const graph = new Graph<string>();
// Add a few nodes with string data
const nodeA = graph.addNode("A");
const nodeB = graph.addNode("B");
const nodeC = graph.addNode("C");
// Connect nodes with bidirectional edges (default)
graph.addEdge(nodeA, nodeB);
graph.addEdge(nodeB, nodeC);
graph.addEdge(nodeC, nodeD);
graph.addEdge(nodeD, nodeE);
// Check if nodes are connected
const connected = graph.areNodesConnected(nodeA, nodeB); // true
// Get neighbors of a node

// Find shortest path from A to C
const { path, distance } = graph.shortestPathDijkstra(nodeA, nodeC);
const aStarResults = graph.astar(nodeA, nodeB);
