Wen plotting dense, largely unconstrained data (i.e. not on a 0-100 scale), I've found a hybrid scatter/density plot to be nice. Basically, for each point you do a kernel density estimation, then color the points according to that. For the sparse data, the scatter plot seems just as useful, but at the dense parts, you seamlessly switch to color as the useful metric.
