<wc-pie-chart id="existing"
              thickness="0.1">
  <wc-pie-slice value="5"
                color="#E64C65"></wc-pie-slice>
  <wc-pie-slice value="5"
                color="#11A8AB"></wc-pie-slice>

</wc-pie-chart>

Configuration

The chart's appearance and behaviour can be changed using attributes.

Adding width will change the dimension of the chart from the default of 150px.

Adding duration will alter the overall duration of the animation in supported browsers (currently only Chrome and Edge) from the default of 2000ms (2 seconds)

Adding delay will delay the start of the animation in supported browsers from the default of 500ms (half a second)

Adding thickness will alter the width of the slices from the default of 20% of the width of the overall chart (setting this to 0.5 will create a pie-chart).

Data

The chart relies upon one or more compulsory <wc-pie-slices>s; these have to have a value and optionally can have a color attribute (a random colour will be assigned if no colour is provided)
