 * @example
 * ```javascript
 * const fBoard = univerAPI.getActiveBoard();
 * const chartInfo = fBoard
 *   .newChart(univerAPI.Enum.ChartTypeString.Column)
 *   .setSource([
 *     ['Quarter', 'Sales'],

 *   ])
 *   .setAbsolutePosition(120, 80)
 *   .setSize(640, 360)
 *   .setTitle('Quarterly sales')
 *   .build();
 * const fChart = await fBoard.insertChart(chartInfo);
 *
 * fChart
 *   .setSubtitle('FY 2026')

 * await fChart.setDataSource([
 *   ['Quarter', 'Sales'],
 *   ['Q3', 210],

 *   .toBuilder(univerAPI.Enum.ChartTypeString.Pie)
