Set a dictionary with the javascript class Circle parameters

        This function sets a default drawing configuration if the user just
        pass the rectangle bounds, but also allows to set each parameter
        individually if the user wish so.

        Args:
            center_lat (float): The circle center latitude
            center_lng (float): The circle center longitude
            radius  (float): The circle radius, in meters
            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.
            fill_color (str): Sets the color of the circle fill using
                hexadecimal color notation
            fill_opacity (float): Sets the opacity of the circle fill
