The source didn't share its exact prompt, so we wrote this from what it describes.

Let's work this out together. I'll tell you what I'm after; help me sharpen the goal before you dive in, and check in with me before anything you can't undo.

Goal: Help me see whether traffic deaths in my state are really going down, using a chart I can trust.

Questions to explore first: Which states and years, and what made you curious (a sign, a news story)?

What I need from you:
- The states to compare ([STATE 1], [STATE 2])
- The years to cover

Rules:
- Start by restating my goal and suggesting 2–3 ways to approach it; recommend one.
- Use official sources (state DOT or NHTSA FARS) and name them.
- Plot deaths per month as a line chart per state.
- Mark months where data is preliminary or missing.
- Add a per-capita version so the states can be compared fairly.
- Don't claim causes; just describe the trend.

Output: Two charts, the data table behind them, and a 3-sentence trend summary with sources, plus 2–3 suggested next steps.

If any of this is unclear, tell me what you have and I'll help fill the gaps.

You'll know it worked when: the chart numbers match the cited source for a few months you spot-check.
