Step 1: Start at the initial node (the root node) of the graph.
Step 2: Visit all the neighbors of the initial node. These are the nodes directly connected to it.
Step 3: After visiting all neighbors of the initial node, move to the next level of nodes. This means you will now visit the neighbors of the nodes you just visited.
Step 4: Continue this process: for each new node you visit, explore all its neighbors before moving on to the next node at the same level.
Step 5: Repeat this process until all nodes in the graph have been visited.
