Apply accessible layout to a plotly figure

Sets fonts, axis styling, hover-label colors, legend position, and an accessible categorical colorway. Targets WCAG 2.1 contrast (1.4.3, 1.4.6, 1.4.11) and resizability (1.4.4). Font sizes are package defaults, not WCAG-mandated minimums. Returns the plotly object so it can stay in a |> chain.

Usage

a11y_layout(p, level = "AA", palette = "dark2_8")

Arguments

p

A plotly object (from plotly::plot_ly or plotly::ggplotly).

level

"AA" or "AAA".

palette

Discrete palette name applied as plotly's colorway. See a11y_palette_list(). Pass NULL to leave plotly's default colors unchanged.

Value

Modified plotly object.
