Oh, good, the moth can graph. But they don't know the notation. Sasha sends the symbols 1 = log10, 2 = log100, and so on for ten or so entries, then the graph of log10 x with just the scale labeled, then a second copy of the graph with the axes labeled as x and y [or the high language equivalent] and the function labeled as y = log10 x.
[I taught a class Mayan numerals once-- it's easier to work out the base 20 part from scratch than the zero symbol-- and I had a colleague who used to teach her students how to make an Incan quipu. But I think this sort of graphing is pretty solidly, well, Cartesian.]
