docstr: Construct a new Line object
  
  Parameters
  ----------
  arg
      dict of properties compatible with this constructor or
      an instance of
      :class:`plotly.graph_objs.contourcarpet.Line`
  color
      Sets the color of the contour level. Has no effect if
      `contours.coloring` is set to "lines".
  dash
      Sets the dash style of lines. Set to a dash type string
      ("solid", "dot", "dash", "longdash", "dashdot", or
      "longdashdot") or a dash length list in px (eg
      "5px,10px,2px,2px").
  smoothing
      Sets the amount of smoothing for the contour lines,
      where 0 corresponds to no smoothing.
  width
      Sets the contour line width in (in px) Defaults to 0.5
      when `contours.type` is "levels". Defaults to 2 when
      `contour.type` is "constraint".
  
  Returns
