Density plot option within geom_histogram

[jacobpstein]

Is it possible to add functionality to the StatMirrorCount function such that the "density" stat within the underlying geom_histogram can be applied? While the histogram default is informative, it can be helpful to see the proportion of values as part of a density plot rather than the count. Gelman also notes that histograms technically categorize the data (through bins) and then plot them, which, with enough bins, is fine, but seeing the smooth plot would be helpful.

I seem to go back and forth on an annual cadence as to whether I prefer histograms or densities.

But yes, I think this is a reasonable feature request and will try to tackle it soon
