docs: Set a dictionary with the javascript class Polyline parameters
  
          This function sets a default drawing configuration if the user just
          pass the polyline path, but also allows to set each parameter
          individually if the user wish so.
  
          Args:
              path (list): A list of latitude and longitude point for the
              polyline stroke_color (str): Sets the color of the rectangle
              border using hexadecimal color notation
              stroke_opacity (float): Sets the opacity of the rectangle border
                  in percentage. If stroke_opacity = 0, the border is transparent
              stroke_weight (int): Sets the stroke girth in pixels.
