Data label can be added to a chart series by enabling the visible
option in the dataLabel property.

Accumulation chart provides support for placing the data label either inside or outside the chart.

ReactDOM.render(<App />, document.getElementById("charts"));Note: By default, when the enableRotation is true, the datalabel is rotated along the slice.
Datalabels will be arranged smartly without overlapping with each other. You can enable or disable this feature using
the enableSmartLabels property.

ReactDOM.render(<App />, document.getElementById("charts"));Label content can be formatted by using the template option. Inside the template, you can add the placeholder text
${point.x} and ${point.y} to display corresponding data points x & y value. Using
templateproperty, you can set data label
template in chart.

ReactDOM.render(<App />, document.getElementById("charts"));Connector line will be visible when the data label is placed outside the chart.
The connector line can be customized using the type, color, width, length and dashArray properties
