To highlight it better, we’ll change to logarithmic spacing, where each segment of the vertical axis represents a tenfold increase in tribbles: an increase first from 1 to 10, then from 10 to 100, then from 100 to 1,000, and so on. In other words, we scale the axis by powers of 10 or orders of magnitude. Logarithmic graphs have a wonderful property: they show exponential growth as a perfectly straight line.
