            A chart is configured with 3 properties; <i>type</i>, <i>data</i> and <i>options</i>. Chart type is defined using the <i>type</i> property that accepts <i>pie</i>, <i>doughtnut</i>, <i>line</i>, <i>bar</i>, <i>radar</i> and
            <i>polarArea</i> as a value. The <i>data</i> defines datasets represented with the chart and the <i>options</i> provide numerous customization options to customize the presentation.
