guides
Bind guide specifications to aesthetics.
Accepts named arguments where each key is an aesthetic (e.g., colour, fill) and each value is a guide spec from guide-legend or guide-none. The resulting dictionary threads into the plot spec and is honoured by the legend renderer.
Usage

Examples
Lay the colour legend out across two columns.
#let d = (
(x: 1, y: 1, g: "a"),
(x: 2, y: 2, g: "b"),
(x: 3, y: 3, g: "c"),
)
#plot(
data: d,
mapping: aes(x: "x", y: "y", colour: "g"),
layers: (geom-point(size: 3pt),),
guides: guides(colour: guide-legend(ncolumn: 2)),
width: 10cm,
height: 6cm,
)
Combine guide-axis and guide-none to rotate x ticks and hide the redundant fill legend in one call.
#let d = (
(x: "January", y: 1, g: "a"),
(x: "February", y: 2, g: "a"),
(x: "March", y: 3, g: "b"),
(x: "April", y: 4, g: "b"),
)
#plot(
data: d,
mapping: aes(x: "x", y: "y", fill: "g"),
layers: (geom-col(),),
guides: guides(
x: guide-axis(angle: 30),
fill: guide-none(),
),
width: 10cm,
height: 6cm,
)
