The traces' data tables: 'hidden' for screen readers only (first 100 rows), 'visible' shown below the chart with every row (virtualized), false none. Holochart only (plan E17.3).
keyboard?
boolean
true
Keyboard access: Tab reaches the plot area (the arrows step through the data, + / - zoom) and the legend items. Holochart only (plan E6.5, E17.4).
patterns?
boolean
false
Give bars, histograms, polar bars, filled areas (fillpattern) and pie slices a distinct pattern each, as an encoding redundant with color, unless the trace or template sets one. Holochart only (plan E17.5).
reducedMotion?
boolean | "auto"
"auto"
Snap transitions and drill-down tweens instead of animating them: 'auto' when the user's system asks for reduced motion (the prefers-reduced-motion media query), true always, false never. Holochart only (plan E17.5).
summaries?
boolean
true
Add generated summaries of trends and extremes ("Revenue rises from 1.2M in Jan to 3.4M in Dec") to what screen readers get. Their code loads after the first draw. Holochart only (plan E17.2).
