Using Razor inside Javascript (not MVC)

Question

I'd like to know if in my case I can use razor inside javascript!

<html>
    <head>
    <!--Load the AJAX API-->
    <script type="text/javascript" src="https://www.gstatic.com/charts/loader.js"></script>
    <script type="text/javascript">

    // Load the Visualization API and the corechart package.
    google.charts.load('current', {'packages':['corechart']});

    // Set a callback to run when the Google Visualization API is loaded.
    google.charts.setOnLoadCallback(drawChart);

    // Callback that creates and populates a data table,
    // instantiates the pie chart, passes in the data and
    // draws it.
    function drawChart() {

        // Create the data table.
        var data = new google.visualization.DataTable();
        data.addColumn('string', 'Topping');
        data.addColumn('number', 'Slices');
        data.addRows([
          ['Mushrooms', 3],
          ['Onions', 1],
          ['Olives', 1],
          ['Zucchini', 1],
          ['Pepperoni', 2]
        ]);

        // Set chart options
        var options = {'title':'How Much Pizza I Ate Last Night',
                   'width':400,
                   'height':300};

        // Instantiate and draw our chart, passing in some options.
        var chart = new google.visualization.PieChart(document.getElementById('chart_div'));
        chart.draw(data, options);
      }
    </script>
    </head>

    <body>
        <!--Div that will hold the pie chart-->
        <div id="chart_div"></div>
    </body>
</html>

This is just a basic code from Google that will show a pie chart with static values and I would like to add some variables to the numbers in the chart so that they can change based on data on my page.

data.addRows([
      ['Mushrooms', 3],
      ['Onions', 1],
      ['Olives', 1],
      ['Zucchini', 1],
      ['Pepperoni', 2]
    ]);

Basically this is the part that matters in that case, I would like to swap the numbers in this code to razor variables like for example @number or something, is this possible?

While searching around for some answers I found that adding in the javascript code would make it allow razor but I couldnt make it work, when I did that the chart didnt even show up, just by adding <text> , not even any razor code.

Or if you have experience with Google Charts API and know how to do this in a better way overall!

Yes you can use razor inside of the <script> tag.

<script type="text/javascript">
  data.addRows([
    ['@someRazorString', @someRazorNumber]
  ]);
</script>

also, you can render any .net object using

@{
var jsonSerializerSettings = new JsonSerializerSettings { ContractResolver = new CamelCasePropertyNamesContractResolver() };
<text>
    <script type="text/javascript">
        var someJsObjectOrArray = @Html.Raw(JsonConvert.SerializeObject(Model.someDotNetObjectOrArray, jsonSerializerSettings)));
    </script>
</text>
}
