Creating a wind rose chart

A wind rose chart is created by enabling column stacking option in a series. Though it's not a very common type of chart, it's worth looking at, given that it's based on polar charts.

Consider the following modified code of an example from Chapter 2, Column and Bar Charts, that shows the breakdown of medals earned by leading countries in Olympics 2012. Notice the effect of enabling the column stacking option:

(function() {
  $( '#medal_table' ).highcharts({
    chart: {
      type: 'column',
      polar: true
    },
    title: {
      text: 'Olympics 2012 Medal Table'

    },
    yAxis: {
      title: {
        text: 'Medals',
        y: -45
      }
    },
    plotOptions: {
      column: {
        stacking: 'normal'
      }
    },
    series: [{
      name: 'Gold',
      data: [46, 38, 24, 29, 13...
