A Highcharts Pareto chart made accessible by the MAIDR Highcharts adapter. Two layers are read: the columns, which are the counts, and the cumulative curve drawn over them. Click on the chart and use left and right arrow keys to move between causes, and the layer keys to move between the two readings. The curve's numbers are percentages of the total, not a running count — which is what a Pareto chart is read for, since the point at which it crosses 80% is the answer the chart exists to give.
