chart.data = data;
// Create axes
var categoryAxis = chart.xAxes.push(new am4charts.CategoryAxis());
categoryAxis.dataFields.category = "country";
categoryAxis.renderer.grid.template.disabled = true;
var valueAxis = chart.yAxes.push(new am4charts.ValueAxis());
valueAxis.title.text = "Units sold (M)";
valueAxis.min = 0;
valueAxis.renderer.baseGrid.disabled = true;
valueAxis.renderer.grid.template.strokeOpacity = 0.07;
// Create series
var series = chart.series.push(new am4charts.ColumnSeries());
series.dataFields.valueY = "units";
series.dataFields.categoryX = "country";
series.tooltip.pointerOrientation = "vertical";
