Google图表：将笔画添加到点

Question

I wish to add a stroke around the points in my Google line chart.

From the points-documentation of Google Charts (bottom) we have that:

The following style customizations are available: [...] - stroke-color (Specified as a hex string.) - stroke-width (Specified as a hex string.)

I can't find the documentation of how to add these options. Anyone, who can figure it out?

Borrowing from one of google's examples ( see https://jsfiddle.net/j9sgdr4d/ )

var data = google.visualization.arrayToDataTable
        ([['X', 'Y', {'type': 'string', 'role': 'style'}],
          [1, 3, null],
          [2, 2.5, null],
          [3, 3, null],
          [4, 4, null],
          [5, 4, 'point { size: 18; shape-type: star; fill-color: #a52714'],
          [6, 3, 'point { size: 18; shape-type: star; fill-color: #a52714; stroke-color: #ff0000; stroke-width: 5'],
          [7, 2.5, null],
          [8, 3, null]
    ]);
