## Communication goal

## Data shape

## Chart
- Preferred type(s): Line chart — choose the most honest encoding; recommend a better one if these mislead.
- Output: Tool-agnostic spec code.

## Requirements
- Define encodings (x, y, color, facet), scales, sort order, and axis/number formatting.
- Accessible: colorblind-safe palette, labels and units, no chartjunk.
- Note the single takeaway the chart should make obvious, and the title that states it.
