Antibiotic history and the winning bacteria

We take antibiotics. Bacteria dies, but some lives, evolves and develops a resistance to the antibiotic. To better understand why this is such a problem, Keith Collins for Quartz provides a scrolling history of antibiotic development through a series of charts.

The animated transitions between charts keep you connected through the text. Although this feels more like it should be a stepper. The boxed text kind of gets in the way as you scroll, and at each step the text really only fits in one place anyways. Maybe scrollers work better for mobile?
