Usage Example

@echarts.Pie(echarts.PieConfig{
  Label: "Incident states",
  Series: []echarts.PieSeries{{
    Name: "Incidents",
    InnerRadius: 32,
    OuterRadius: 72,

      {Name: "Resolved", Value: 28},

A zero outer radius renders at 75%. A zero inner radius renders a full pie; set both radii for a donut. Rose mode remains off unless selected.
