Pie & donut in : Shared baseline
Playfair 1801; Florence Nightingale’s coxcomb is a polar cousin, 1858 Yes if one claim is visible at a glance Clip Pie & donut from a paper and keep the axis sentence, not the colour.

Playfair 1801; Florence Nightingale’s coxcomb is a polar cousin, 1858 Yes if one claim is visible at a glance in Meta, Google and retail print; otherwise link to a full figure. Yes for lab reports and poster boards if axes, units and a source line are present. Excel or Google Sheets or PowerPoint; export SVG/PDF.
Do not rely on hue alone. Label directly and check greyscale. Pie & donut: honour angle (and area) of a circle slice, and switch when many similar slices, 3-D pie, or comparing two pies. The core mark of Pie & donut is angle (and area) of a circle slice. two to five parts that sum to a meaningful whole
The eye compares length and position more accurately than area. PowerPoint, Excel or Google Sheets and Meta, Google and retail print share the same geometry. Decoration rarely persuades; it slows reading. Perspective distortion wrecks comparison. Keep it flat. Rainbow defaults fail color-blind viewers and grey print. Change Excel or Google Sheets defaults.
Keep axis, unit, and year. If “Shared baseline” is the axis, the figure is 1801 and the year is .1801
