show density in scatter

Using scatter, it seems less probably (numerous) points show just as much as
more probable points. Can anyone suggest a good way to emphasize the more
probable points?

I was thinking maybe the easy way is just scale down the markers. Drawback may
be too many points plotted.

Colors would be nice, but I guess that would be more work?

This is what hexbin is for, although it takes the additional step of showing points on a grid, not at their original precise locations.

You could try something like the scatter+histograms shown here:

Takes a bit more space, but the colors aren’t as important.

Another idea: set alpha to something less than 1, maybe something like 0.3; then superimposed markers will show up darker than lone markers.
