"Stoplight diagram" is WAY to nebulous to expect to find something that even should be comparable to your assigned task. But even so, you need to show YOUR best effort to solve YOUR homework. Asking someone to post their solution so that you can "compare" it to "your" (unshown) solution is a time-worn tactic used to try to trick others into doing your homework for you.
Since you apparently don't have the time to even make an attempt of your own, I'll do you one better. Post the contact information for your course and instructor and I'll send them everything needed to ensure you get all the credit you deserve.
