How do you draw a line between two points in google geo chart?

I want to draw a line between two points (zip codes in this case) on map using googles geochart function. Is that possible? For example, I would like to have a line drawn between zip 07206 and 78746 below:

    <html>
  <head>
    <script type='text/javascript' src='https://www.google.com/jsapi'></script>
    <script type='text/javascript'>
        google.load('visualization', '1', { 'packages': ['geochart'] });
        google.setOnLoadCallback(drawMarkersMap);

        function drawMarkersMap() {
            var data = google.visualization.arrayToDataTable([
              ['Region', 'Total'],
              ['07206', 500],
              ['78746', 250],
              ['90040', 1000],
            ]);

            var options = {
                sizeAxis: { minValue: 0, maxValue: 100 },
                region: 'US', // United States
                resolution: 'provinces',
                displayMode: 'markers',
                colorAxis: { colors: ['#e7711c', '#4374e0'] } // orange to blue
            };

            var chart = new google.visualization.GeoChart(document.getElementById('chart_div'));
            chart.draw(data, options);
        };
    </script>
  </head>
  <body>
    <div id="chart_div" style="width: 900px; height: 500px;"></div>
  </body>
</html>
