Points

Property	Default	Meaning
points	[]	Marker positions; null and nonfinite values are omitted
point-size	px(6)	Marker size, pair, or (point, index) => size callback
shape	Circle	Marker Element or (point, index) => Element callback
children	—	Single marker Element, as an alternative to shape
space	Automatic	Use ambient data coordinates or local geometry

Repeat a marker at each {x,y} or [x,y] in points. Projected graphs also accept named numeric records such as {theta, r} and {x, y, z}. The forms can be mixed. Null/nonfinite entries are omitted without changing callback indices. Positions use ambient Graph coordinates or local fractions outside it.

point-size is full marker diameter/size, default px(6). Scalar fractions use the shorter frame side; {x,y} or [x,y] sizes resolve per axis. It may be a (point,index) function returning a scalar or pair. shape is an Element or (point,index) function; the default is Circle.

Pass a reusable marker as a single child or through shape. Use the shape callback for per-point markers. Supplying both a marker child and shape, or multiple marker children, is an error.

Callbacks receive complete frozen source records; tuples expand to {x,y}. They execute once at construction, retaining original indices. Shapes receive exact marker dimensions and a cleared data context, then are centered on their points. The same immutable shape can be reused everywhere. Rotate and TransformBox pass those dimensions through to their wrapped shape before transforming it. The default circle uses the theme foreground fill and no stroke. Custom shapes use normal style inheritance and their own styling; no marker fill or stroke defaults are added. Explicit fill and stroke on Points are inherited by shapes unless the shapes override them. Return styled shapes for individual colors. Marker sizes do not contribute to data limits.
