Axis of Evil

Each round shows a chart making a bold claim through a visual deception. First tag the trick it uses. Then rebuild the honest version by toggling fixes, start the axis at zero, show the full range, un-invert the axis, or scale areas honestly, and the misleading message collapses. The bigger the spin you dismantle, the higher you score.

• Deceptions include truncated axis, cherry-picked range, area distortion and inverted axis.
• Tag correctly and rebuild fully for the most points.
• A run is five charts with a running total.

• Desktop: click a deception tag, then toggle the rebuild checkboxes and Submit.
• Phone & tablet: tap the tag and the fix toggles, fully touch-friendly.

• Daily: a shared seeded set of charts.
• Practice: fresh randomized charts each run.

• Check the y-axis start and range before reading any trend.
• If bubbles or shapes encode value, suspect area distortion and apply honest scaling.

Axis of Evil teaches you to spot and undo the classic ways graphs mislead, from truncated axes to bad scales.

• Skills: data literacy, misleading axes, reading graphs critically
• Best for: roughly grades 7–12 (ages 12+)
• For parents & teachers: the tricks crooked charts use.

Tagging the trick and then rebuilding the honest version is the study of the misleading graph — truncated axes, inconsistent scales, volumes standing in for lengths.

Requiring the repair, not just the diagnosis, is the original demand.

Spotting a distorted chart is easy once you are looking for it; the harder skill is knowing what the undistorted version would have shown, because a truncated axis does not invent a trend so much as exaggerate a real one. Rebuilding it tells you how much of the story survives.
