This is a straight plot of the bivariate means of 38 different groups of primates. We've already stripped out the data scatter around each mean, but we want to highlight where each group lies in the 2-dimensional space. We haven't found a more effective way to illustrate this in a single plot than using a simple bivariate scatter.
