/**
Polar area charts are similar to pie charts, but each segment has the same angle - the radius of the segment differs depending on the value.

This type of chart is often useful when we want to show a comparison data similar to a pie chart, but also show a scale of values for context.

##### Example

    <chart-polar-area data="{{data}}"></chart-polar-area>

    ...

    this.data = {
      datasets: [{
        data: [
          11,
          16,
          7,
        ],
        backgroundColor: [
          "#FF6384",
          "#4BC0C0",
          "#FFCE56",
        ],
        label: 'My dataset' // for legend
      }],
      labels: [
        "Red",
        "Green",
        "Yellow"
      ]
    };
