  const predecessors = {};
  const unvisited = new Set(Object.keys(graph));

  // Initialize distances
  for (let node in graph) {
    distances[node] = node === start ? 0 : Infinity;
  }

  while (unvisited.size > 0) {
    let currentNode = null;
    for (let node of unvisited) {
      if (currentNode === null || distances[node] < distances[currentNode]) {
        currentNode = node;
      }
