I'm the author, thanks for suggestions on improving the charts, especially regarding the marginal histograms. Just a couple of questions: What color maps would you use for those kde plots? I know seaborn by default uses the Freedman-Diaconis rule to create bins for the hexbin plot. But, what suggestions do you have for binning?
