    * In order to set the rotation center for rotation, set x and y to 0 and
    * use `translateX` and `translateY` attributes to position the element
    * instead.
    *
    * Attributes frequently used in Highcharts are `fill`, `stroke`,
    * `stroke-width`.
    *
    * @sample highcharts/members/renderer-rect/
    *         Setting some attributes
    *
    * @example
    * // Set multiple attributes
    * element.attr({
    *     stroke: 'red',
    *     fill: 'blue',
    *     x: 10,
    *     y: 10
    * });
    *
    * // Set a single attribute
    * element.attr('stroke', 'red');
    *
    * // Get an attribute
    * element.attr('stroke'); // => 'red'
    *
    * @function Highcharts.SVGElement#attr
    *
    * @param {string|Highcharts.SVGAttributes} [hash]
    *        The native and custom SVG attributes.
    *
    * @param {number|string|Highcharts.SVGPathArray} [val]
    *        If the type of the first argument is `string`, the second can be a
    *        value, which will serve as a single attribute setter. If the first
    *        argument is a string and the second is undefined, the function
    *        serves as a getter and the current value of the property is
    *        returned.
    *
    * @param {Function} [complete]
    *        A callback function to execute after setting the attributes. This
    *        makes the function compliant and interchangeable with the
    *        {@link SVGElement#animate} function.
    *
    * @param {boolean} [continueAnimation=true]
    *        Used internally when `.attr` is called as part of an animation
    *        step. Otherwise, calling `.attr` for an attribute will stop
    *        animation for that attribute.
    *
    * @return {Highcharts.SVGElement}
    *         If used as a setter, it returns the current
    *         {@link Highcharts.SVGElement} so the calls can be chained. If
    *         used as a getter, the current value of the attribute is returned.
