Recommend the right chart for this data

Recommend the right chart for this data. Don't just pick one — tell me why.

The data:
{{paste data shape — what columns, what rows, how many}}

The story I want to tell:
{{the question or insight the chart should make obvious}}

Audience:
{{who's reading — exec? engineer? customer?}}

Output:
1. **The recommended chart type** and why
2. **One alternative** worth considering and the tradeoff
3. **What to put on x vs y** — and why this orientation
4. **What to highlight** — color, annotation, emphasis on the key data point
5. **What to leave out** — series that dilute the story
6. **Common mistakes** for this chart type — things that look clever but mislead

If the data doesn't justify a chart at all (e.g., it's better as a single number with context), tell me to skip the visualization.
