Twenty years ago, my father gave me my first paper wheel chart. An information-rich rotating nutrition guide marketed to physicians and druggists in the 1940s, it was dubbed The Wheel o' Life. I loved its bold design, neat functionality, and kitschy terminology (phosphorus was labeled "the life-thought mineral"; chlorine, "the laundry man mineral"). It wasn't long before I became an avid collector of other such charts. The computers of their day, volvelles, as they're called, originated in medieval manuscripts as tools for representing data.
