bizcharts example : Doughnut Chart

Chart UI

chart_examples

key codes explaintion:

<Coord type='theta' innerRadius={0.45} />
without 'innerRadius={0.45}', UI will looks like:
chart_examples_full

without below codes, UI will looks like:

<Geom select={[false,{}]} type='intervalStack' position='percent'
  color={['type', ['rgba(255, 255, 255, 0)']]}
  style={{stroke: 'rgba(152,191,182,1)', lineWidth: 1}}>
</Geom>
