Data-ink in : Mark
Data-ink decides what is being compared in under “Mark.” The figure that must stay on the axis is 1983. Drawing it larger does not create a unit. Look first for a cut axis and a missing key. Axis names, units, a source line. Markers read them.
When the story is: auditing slides, dashboards and science figures. Skip it in cases like: a poster that must shout from three metres — ads may keep some junk on purpose. Edward Tufte, The Visual Display of Quantitative Information, 1983 the share of ink that represents data versus decoration
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.
Data-ink: honour the share of ink that represents data versus decoration, and switch when a poster that must shout from three metres — ads may keep some junk on purpose. The core mark of Data-ink is the share of ink that represents data versus decoration. auditing slides, dashboards and science figures
