# Ask AI to explain a difficult chart without inventing its data

Bound visual inspection and request original data when exact values are unavailable.

Use the supplied source as authority. Check the account supports the actual file or image operation before attempting it.

## Task instruction

Explain this permitted chart for [reader and question].
First list the title, axes, units, categories and values you can actually
read. Mark unreadable or absent information explicitly. Describe visible
relationships without inventing exact data, dates, definitions or causes.
If an exact calculation requires source data, ask for it. Keep any rough
visual estimate clearly separate from a supplied measured value.
Do not treat an attractive chart as evidence of a causal explanation.

## Source boundaries

- Visible values
- Source period
- Cause not supplied

## Review and correction

A chart can establish a pattern without establishing its cause. Put an explanation forward as a question or proposal, not a finding.

Use this supplied chart-source table for exact values. Check its period,
categories, units and scope against the image. Replace unsupported visual
estimates with source values and retain unresolved mismatches.
Do not invent a cause. Show any calculation and its inputs, with a
plain-language explanation that preserves source qualifications.

Use references/practice-source.json for the labelled example. The practice HTML is a local teaching tool; it does not call an AI service. Apply this method to the user's supplied facts rather than copying fictional example values. Do not infer approval or permission to publish.
