Amcharts向下钻取到国家/地区，添加可点击的链接

// 创建MapChart实例
var chart = am4core.create("chartdiv", am4maps.MapChart);

// 设置地图数据
chart.geodata = am4geodata_worldLow;

// 设置投影方式
chart.projection = new am4maps.projections.Miller();

// 创建地图系列
var polygonSeries = chart.series.push(new am4maps.MapPolygonSeries());
polygonSeries.useGeodata = true;

// 配置地图区域样式
var polygonTemplate = polygonSeries.mapPolygons.template;
polygonTemplate.fill = am4core.color("#74B266");
polygonTemplate.stroke = am4core.color("#FFFFFF");
polygonTemplate.strokeWidth = 0.5;

// 启用点击事件
polygonTemplate.events.on("hit", function(ev) {
  var country = ev.target.dataItem.dataContext;
  // 根据点击的国家/地区信息进行相应操作，例如跳转到链接页面
  window.location.href = "https://example.com/" + country.id;
});

// 渲染地图
chart.render();
