      Logarithmically scaled image. I’ll leave the determination of the base of the Log as an exercise for the viewer.

        That’s what I thought, so I investigated.

        The base of the log can be accounted for by a constant scale factor, because, for example, if n is the number of bison,

        log10(n)
        = log10(e^ln(n))
        = ln(n) log10(e) and log10(e) is a constant.
        This change of base is a linear scale on the logs.

        Hence we can just take log 10 of the numbers of bison, and scale the answer by a constant factor which is log10(correct base), getting
        7.778, 2.477 and 4.477
        Scale that by about 2 = log10(100) to match the 5 bison in the middle pictogram, and there should be
        16, 5, 9 bison on a logarithmic scale.

        The diagram is also wrong if it’s logarithmic.
