    <p class="highcharts-description">The following chart demonstrates some Accessibility features of Highcharts, including use of the <code>exposeAsGroupOnly</code> option.
    The <code>exposeAsGroupOnly</code> is set to true in this demo for two of the series, which means that only the series element is exposed to a screen reader, not its points.</p>
