svg_polyline: Addition of an 'polyline' element
In omsvg: Build and Transform 'SVG' Objects

Description Usage Arguments Value Examples

The svg_polyline() function adds a polyline to an svg object. The polyline is drawn by connecting a series of points with straight lines. The points can be provided as a vector that's exactly divisible by two, or, as a formatted string that adheres to the specification of the points attribute of the SVG <polyline> tag. All point positions are in units of px.

svg_polyline(
  svg,
  points,
  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.
`points`	A numeric vector of points (with alternating values for `x` and `y` positions) that define the polyline. This can also be a single-length character vector that holds the formatted points string (space-separated `x` and `y` values, and comma-separated points).
`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.
