On clicking the specific label in Canvasjs Pie chart, pass the clicked label to Flask for further processing

Question

I am working with pie charts using Canvasjs and I want to make it clickable so that if the specific label is clicked it will send the clicked label value to the flask so that I can process that value in the flask also redirect me to the other page
My Chart Code on the index.html page

{%extends "master.html"%}

{%block chart%}
<script>
  window.onload = function () {

var chart = new CanvasJS.Chart("chartContainer", {
    animationEnabled: true,
     exportEnabled: false,
  theme: "light1", // "light1", "light2", "dark1", "dark2"
   backgroundColor: "transparent",
    **data: [{
      click: function (e) {
                            var dataPoint = e.dataPoint.label;
                            window.open({{url_for('jazz_index')}}, "_blank");
                    },**
        type: "doughnut",
        startAngle: 20,
        //innerRadius: 10,
        indexLabelFontSize: 17,
        indexLabelFontColor: "white",
        indexLabel: "#percent%",
        toolTipContent: "<b>{label}:</b> {y} (#percent%)",
        dataPoints: [

        {%for outgoing_number,outgoing_call_type in outgoing_calls%}
        { y: {{outgoing_call_type}}, label: "{{outgoing_number}}" },
            {%endfor%}
            ]
    }]
});
chart.render();
}
</script>

{%endblock%}

{%block body%}
<div class="card-body" id="chartContainer" style="min-height: 250px; height: 250px; max-height: 250px; max-width: 90%;">
                    </div>
{%endblock%}

In this code, I am making a pie chart and I want to pass variable dataPoint to the flask route jazz_index when the specific bar is clicked on the pie chart and I also want to know how to access that variable value in the route jazz_index so that I can process that dataPoint value and redirect the chart to the new page (jazz_index.html) which contains the information related to that dataPoint.

This is my jazz_index route

    @app.route('/jazz', methods=['GET', 'POST'])
def jazz_index():
    return render_template('jazz_index.html')

Please help me out with some code. Thanks in advance
