"This is a terribly misleading graphic which uses a non-zero-based Y axis to make a 1% difference seem much larger. I recommend Tufte's 'The Visual Display of Quantitative Information'." — Jeff Dean

The chart shows U.S. steel production of ~80.7 Mt in 2024 versus ~81.7 Mt in 2025 — roughly a 1% increase. By starting the Y-axis at 80.2 instead of 0, the green bar appears approximately 3 times taller than the red bar, wildly exaggerating the actual difference.

A zero-based axis would reveal the truth: both bars would be nearly identical in height.
