The instructions your model reads when the skill loads.
A table of numbers hides the story; a chart shows it. This skill turns data into a clean, correctly-typed
chart — a trend as a line, a comparison as bars, a composition as a pie/doughnut — emitted as a
small JSON spec inside a ```chart block that renders live in the playground (and exports as PNG).
Ask for these only if they aren't already provided:
If the data implies the wrong chart type for the goal, pick the right type and say why.
A one-line read — the takeaway the chart makes obvious.
