Seaborn-style distribution plots
Distribution plots in the style of seaborn’s example gallery, drawn with
plotpress’s own methods – kdeplot, ecdfplot, rugplot and the
inner/cut options on violinplot. These take plain arrays rather
than a tidy dataframe, so there is no pandas or seaborn dependency; the
semantic-mapping API (hue=, FacetGrid) is deliberately not replicated.
