Legend schema wrapper Properties of a legend or boolean flag for determining whether to show it.

Parameters:

ariabool, dict, ExprRef

A boolean flag indicating if ARIA attributes should be included (SVG output only). If false, the “aria-hidden” attribute will be set on the output SVG group, removing the legend from the ARIA accessibility tree.
