When I tell a human to analyze the data, I sure don't expect them to interpret it as "write code to graph it to a screen you can't see". You found the problem but glossed right over it.

It was told to analyze and then it did a bad job of analyzing. I don't care if an LLM expert expects this already, it's worth pointing out to everyone else. It's not PEBKAC.
