Answer 1

The sunburst chart requires the following module modules/sunburst.js.

Sunburst.js location: https://code.highcharts.com/modules/sunburst.js

API Reference: https://www.highcharts.com/docs/chart-and-series-types/sunburst-series

Answer 2

You need to import and initialize the sunburst module:

import * as Highcharts from 'highcharts';
import HC_sunburst from 'highcharts/modules/sunburst';
HC_sunburst(Highcharts);
