mark_circle: Circle mark

In vegalite: Tools to Encode Visualizations with the 'Grammar of Graphics'-Like 'Vega-Lite' 'Spec'

Description

Circle and square marks are similar to point mark, except that (1) the shape value is always set to circle or square (2) they are filled by default.

Usage

mark_circle(vl, size = NULL, opacity = NULL, filled = NULL,
  color = NULL, fill = NULL, stroke = NULL)

Arguments

vl	a Vega-Lite object
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.
opacity	0.0-1.0
filled	whether the shape's color should be used as fill color instead of stroke color.
color	color of the mark – either fill or stroke color based on the filled mark config.
fill	fill color. This config will be overridden by color channel’s specified or mapped values if filled is true.
stroke	stroke color. This config will be overridden by color channel’s specified or mapped values if filled is false.
