Distribution & count figures

Before a model, look at the data. This part collects the figures that describe a single variable or a simple count: how a measurement is spread, where it clusters, how a category breaks down. They are the plots you make first, to catch the skew or the outlier or the empty cell before it surprises you in an analysis.

The histogram and density chapters show the shape of a continuous measurement; box plots compare that shape across groups; the bar chapter handles counts and proportions. Two of these – density and box plots – have no hvtiPlotR helper, so there we build the figure from bare ggplot2 and apply the house theme, and say so, so the result still sits comfortably next to the rest of the catalog.
