Teach a chart's argument through its data relationships

Using [CHART DATA], [CHART CLAIM], and [LEARNER LEVEL], create a lesson that states the axes, units, comparison groups, and trend in words. Ask learners to test the claim against two specific values and one plausible alternative explanation. Provide a learner-facing text table and question about missing data, followed by a separately labelled teacher key. In interactive use, withhold the key until the learner has answered. Do not invent unsupplied points or infer causation from correlation. Check every numerical statement against the supplied data and mark unreadable values as unknown.
