             *
             * The common pattern when placing a shape is:
             * - Create the SVGElement and add it to the DOM. In styled mode, it will
             *   now receive a stroke width from the style sheet. In classic mode we
             *   will add the `stroke-width` attribute.
             * - Read the computed `elem.strokeWidth()`.
             * - Place it based on the stroke width.
             *

             *         CSS or by attributes) is based on `em` or other units, the pixel
             *         size is returned.

         * {@link Highcharts.Chart#series|series} property that is a collection of all
         * the chart's series. The point objects and axis objects also have the same
         * reference.

         * Another way to reference the series programmatically is by `id`. Add an id
         * in the series configuration options, and get the series object by
         * {@link Highcharts.Chart#get}.
         *
         * Configuration options for the series are given in three levels. Options for

         * [plotOptions.series](https://api.highcharts.com/highcharts/plotOptions.series)
         * object. Then options for all series of a specific type
         * are given in the plotOptions of that type, for example `plotOptions.line`.
         * Next, options for one single series are given in the series array, or as
         * arguments to `chart.addSeries`.
         *
         * The data in the series is stored in various arrays.
         *
         * - First, `series.options.data` contains all the original config options for
         *   each point whether added by options or methods like `series.addPoint`.
         *
         * - Next, `series.data` contains those values converted to points, but in case
         *   the series data length exceeds the `cropThreshold`, or if the data is
         *   grouped, `series.data` doesn't contain all the points. It only contains the

         *
         * 1. An array of numerical values. In this case, the numerical values will be
         *    interpreted as `y` options. The `x` values will be automatically
         *    calculated, either starting at 0 and incremented by 1, or from
         *    `pointStart` * and `pointInterval` given in the series options. If the
         *    axis has categories, these will be used. Example:
         *    ```js
         *    data: [0, 5, 3, 5]
         *    ```
         *
         * 2. An array of arrays with 2 values. In this case, the values correspond to
         *    `x,y`. If the first value is a string, it is applied as the name of the
         *    point, and the `x` value is inferred.
         *    ```js
         *    data: [
         *        [0, 9],
         *        [1, 7],
         *        [2, 6]
         *    ]
         *    ```
         *
         * 3. An array of objects with named values. The following snippet shows only a
         *    few settings, see the complete options set below. If the total number of
         *    data points exceeds the series'
         *    [turboThreshold](#series.area.turboThreshold), this option is not
         *    available.
         *    ```js
         *    data: [{
         *        x: 1,
         *        y: 9,

         *    point, and the `x` value is inferred.

         *    data: [
         *        [0, 0],
         *        [1, 8],

         *    few settings, see the complete options set below. If the total number of
         *    data points exceeds the series'
