Ray

Property	Default	Meaning
origin	[0.5, 0.5]	Ray origin
angle	0	Screen-space direction in degrees, clockwise positive
length	0.5	Distance relative to the shorter side, or a px/em length
space	Automatic	Use ambient data coordinates or local geometry

A finite ray from origin at a screen-space angle in degrees (positive clockwise). Defaults: center origin, angle 0, length 0.5 of the shorter frame side. length is a layout length; only the origin contributes data bounds. Use Arrow with from/to for a data-vector endpoint.

Point inputs accept {x,y} or [x,y]; see Point values.

Inside Graph, numeric geometry uses data coordinates; outside it, geometry uses local fractions/px/em. space="local" opts out of an ambient graph, and space="data" requires one. Pixel strokes keep their size.

Projected point inputs also accept named numeric records such as {theta, r} or {x, y, z}; GeoMap uses {lon, lat}. Every dimension reaches the projection. See Projections for units and visibility rules.
