That is nice! Any way to group driver championships into different eras, maybe by engine formula in horizontal rows. For example 1.5L, 3.0 L, turbo era 1.0, naturally aspirated 3.5, NA 3.0, NA2.4, turbo era 2.0. But easier said than graphically done. Already looks great now.
Is higher res available free, or only for sale? Not a complaint, just a question.
