charts.downsample
Reduce a long series to a few points that keep its visual shape, by Largest-Triangle-Three-Buckets (LTTB).
downsample in Python
charts.stack
Stack several series for stacked bars and areas: on zero, normalised to 100%, or diverging around zero.
stack in Python
charts.histogram-bins
Bin values into histogram bins on round edges, by Sturges' rule, Freedman-Diaconis, or a fixed width.

A group of 5:
axis_from_ticks, number_axis, time_axis, band_axis, grid_lines
charts.color
Hex colours to RGB and back, and sRGB channels to linear light and back, identically in every language.
A group of 4:
