svg_circle: Addition of a 'circle' element
In omsvg: Build and Transform 'SVG' Objects

Description Usage Arguments Value Examples

The svg_circle() function adds a circle to an svg object. The position of the circle is given by x and y, and this refers to the center point of the point of the circle. The diameter of the circle is given in units of px.

svg_circle(
  svg,
  x,
  y,
  diameter,
  stroke = NULL,
  stroke_width = NULL,
  fill = NULL,
  opacity = NULL,
  attrs = list(),
  anims = list(),
  filters = list(),
  id = NULL
)

`svg`	The `svg` object that is created using the `SVG()` function.
`x, y`	The `x` and `y` positions of the center of the circle to be drawn. The `x` and `y` values are relative to upper left of the SVG drawing area.
`diameter`	The diameter of the circle shape in units of `px`.
`stroke`	The color of the stroke applied to the element (i.e., the outline).
`stroke_width`	The width of the stroke in units of pixels.
`fill`	The fill color of the element.
`opacity`	The opacity of the element. Must be a value in the range of `0` to `1`.
`attrs`	A presentation attribute list. The helper function `svg_attrs_pres()` can help us easily generate this named list object. For the most part, the list's names are the presentation attribute names and the corresponding values are the matching attribute values.
`anims`	An animation directive list for the element. This should be structured using the `anims()` function.
`filters`	A filter directive list for the element. This is easily created by using a list of `filter_*()` functions (e.g., `list(filter_gaussian_blur(2), filter_drop_shadow(2, 2))`).
`id`	An optional ID value to give to the built tag. This is useful for modifying this element in a later function call or for interacting with CSS.

An svg object.

      diameter = 40,
      stroke = "magenta",
      fill = "olive"
    )
