	Sounds like a histogram on a function of (x, y) -- you may need to play
with it to get tolerances suitable for binning, and calculate the Z by
scanning the input data.

	What are the domain ranges of X and Y? How many bins in X and Y?

initialize Z array [x-bins, y-bins] <- 0
for (x, y) in zip(x-data, y-data)
	convert x and y to bin indices
	increment Z[x-index, y-index]
plot Z (mapped to a color scale, dot size, whatever) on a grid of x-bins,
y-bins
