A point mark represents each data point with a symbol.

Usage

mark_point(vl, shape = "circle", size = NULL, opacity = NULL,
  filled = NULL, color = NULL, fill = NULL, stroke = NULL)

Arguments

vl	Vega-Lite object
shape	The symbol shape to use. One of circle, square, cross, diamond, triangle-up, or triangle-down. Default value: circle.
size	The pixel area each the point. For example: in the case of circles, the radius is determined in part by the square root of the size value.
