Check axes and units
Confirm what is measured, in what units, and whether axes start at zero where appropriate.
Watch scaling tricks
Truncated axes and stretched scales can exaggerate or hide differences.
Look for uncertainty
Prefer charts with error bars or ranges when variability matters.
Match chart to question
Use lines for time trends, bars for categories, and avoid 3D effects.
