A radar chart is a way of showing multiple data points and the variation between them.

They are often useful for comparing the points of two or more different data sets.

##### Example

    <chart-radar data="[[data]]"></chart-radar>

    ...

    this.data = {
      labels: ["Eating", "Drinking", "Sleeping", "Designing", "Coding", "Cycling", "Running"],
      datasets: [
          {
            label: "My First dataset",
            backgroundColor: "rgba(179,181,198,0.2)",
            borderColor: "rgba(179,181,198,1)",
            pointBackgroundColor: "rgba(179,181,198,1)",
            pointBorderColor: "#fff",
            pointHoverBackgroundColor: "#fff",
            pointHoverBorderColor: "rgba(179,181,198,1)",
            data: [65, 59, 90, 81, 56, 55, 40]
          },
          {
            label: "My Second dataset",
            backgroundColor: "rgba(255,99,132,0.2)",
            borderColor: "rgba(255,99,132,1)",
            pointBackgroundColor: "rgba(255,99,132,1)",
            pointBorderColor: "#fff",
            pointHoverBackgroundColor: "#fff",
            pointHoverBorderColor: "rgba(255,99,132,1)",
            data: [28, 48, 40, 19, 96, 27, 100]
          }
        ]
      };
