/**
 *
 * This lightweight library allows you to create "pie" and "donut" charts easily. 100% Tests-covered
 *
 * The chart component has very flexible settings. It can accept a passed size
 * or automatically adjust to the size of the parent component.
 * Moreover, this component is accessible.
 *
 * More information about all props you can find in the repo: https://github.com/garvae/react-pie-donut-chart
 *
 *
 * Component accept props type of 'PieDonutChartProps'.
 * @component
 * @param { PieDonutChartProps } props
 *
 * You can import 'PieDonutChartProps' type if you need:
 * ```typescript jsx
 * import { PieDonutChartProps } from 'PieDonutChart';
 * ```
 *
 * Returns <svg> chart.
 * @returns {JSX.Element}
 *
 *
 *
 * @example - basic usage. More examples: https://github.com/garvae/react-pie-donut-chart
