Graphs that cause DFS and BFS to process nodes in the exact same order
Assume our BFS and DFS have the rule to start from a specific node and both of them then visit the node with the lowest degree:

Start from left most black node, then both (BFS and DFS) traversals will visit left most red node, then they will visit next black node, and so on. To make it more general, you could add some paths in between triangles, or add star after finishing triangles.
