Accessible viz in : Fit
Accessible viz decides what is being compared in under “Fit.” The figure that must stay on the axis is 1917. Drawing it larger does not create a unit. Look first for a cut axis and a missing key. Accessible viz: honour redundant channels: position, pattern, label, not hue alone, and switch when relying on red/green alone to mean bad/good.
When the story is: public dashboards, exams, print in grey, legal slides. Skip it in cases like: relying on red/green alone to mean bad/good. Ishihara plates 1917; WCAG 2 contrast; Okabe–Ito palettes for deuteranopia redundant channels: position, pattern, label, not hue alone 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. The core mark of Accessible viz is redundant channels: position, pattern, label, not hue alone.
public dashboards, exams, print in grey, legal slides 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.
Read Accessible viz as , “Fit,” and 1917. A bar with no unit is not those three.1917
