AmCharts 4 Donut Graph - HyperLink for Custom URL

Question

I'm unable to get a hyperlink to this donut chart in amcharts4. I made it successfully using amcharts 3 but am not getting it in amcharts4.

Please let me know what I am doing wrong.

I also referred to another documentation but was unable to get help from it.

Here is my script:

am4core.ready(function() {

// Themes begin
am4core.useTheme(am4themes_animated);
// Themes end

var chart = am4core.create("chartdiv", am4charts.PieChart3D);
chart.hiddenState.properties.opacity = 0; // this creates initial fade-in

chart.data = [
  {
    country: "India",
    litres: 501.9,
    url:"amcharts.com/docs/v4/tutorials/clickable-links-in-tooltips/"
  },
  {
    country: "Czech Republic",
    litres: 301.9,
    url:"amcharts.com/docs/v4/tutorials/clickable-links-in-tooltips/"
  },
  {
    country: "China",
    litres: 201.1,
    url:"amcharts.com/docs/v4/tutorials/clickable-links-in-tooltips/"
  },
  {
    country: "Germany",
    litres: 165.8,
    url:"amcharts.com/docs/v4/tutorials/clickable-links-in-tooltips/"
  },
  {
    country: "Australia",
    litres: 139.9,
    url:"amcharts.com/docs/v4/tutorials/clickable-links-in-tooltips/"
  },
  {
    country: "Japan",
    litres: 128.3,
    url:"amcharts.com/docs/v4/tutorials/clickable-links-in-tooltips/"
  }
];


chart.innerRadius = am4core.percent(40);
chart.depth = 120;

chart.legend = new am4charts.Legend();

var series = chart.series.push(new am4charts.PieSeries3D());
series.dataFields.value = "litres";
series.dataFields.depthValue = "litres";
series.dataFields.category = "country";
series.slices.template.cornerRadius = 5;
series.colors.step = 3;
series.urlField= "url";
series.urlTarge= "_blank"

}); // end am4core.ready()

Here is the HTML Part:

<div id="chartdiv"></div>

And The Css

<style>
#chartdiv {
  width: 100%;
  height: 500px;
}

</style>

You need to use property binding and bind the Slice's url property to the "url" key in your data, e.g.

series.slices.template.propertyFields.url = "url";
series.slices.template.urlTarget = "_blank";

Demo:

If "url" is present in the data, the slice will have their mouse cursor change to a pointer on hover and clicking it will take you to a link in a new window.
