I could make the marker, draw the lines, and move the turtle around appropriately
to make a reasonable plot, but the thing I'm wondering about is the scale of the plot.
It should be easy enough to modify later if it's a problem, but I'm wondering if I should
have planned ahead for a plot with so many points, the whole thing should be resized.
I'm not 100% sure how I'm going to do the increment for the axis label yet; it's easy
enough to calculate the difference and turn that into, say, 5 equal divisions, but I
haven't quite decided how I should deal with rounding the number out so it's not something
like 63, 154, 245, 336, 427, 518. It's not the worst thing in the world if that's the output
but I wouldn't be particularly happy with how it's presented.
