A persuasive chart is trying to fool you. Name its trick, then flip the right switches to rebuild it honestly and watch its spin evaporate.

How to play
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.
Controls
Desktop: click a deception tag, then toggle the rebuild checkboxes and Submit.
Phone & tablet: tap the tag and the fix toggles, fully touch-friendly.
Game modes
Daily: a shared seeded set of charts.
Practice: fresh randomized charts each run.
Tips & strategy
Check the y-axis start and range before reading any trend.
If bubbles or shapes encode value, suspect area distortion and apply honest scaling.
