 * Fluent, type-specific Builder for Line Charts.

 * @example Sheet
 * ```ts

 * const chartInfo = fWorksheet
 *   .newChart(univerAPI.Enum.ChartTypeString.Line)
 *   .setSource('A1:D8')
 *   .setLineStyle({ width: 2 })

 * await fWorksheet.insertChart(chartInfo);

 *
 * @example Doc
 * ```ts
 * const fDocument = univerAPI.getActiveDocument();
 * const chartInfo = fDocument
 *   .newChart(univerAPI.Enum.ChartTypeString.Line)
 *   .setSource([['Month', 'Sales'], ['Jan', 120], ['Feb', 180]])
 *   .setLineStyle({ width: 2 })
 *   .build();

 * @example Slide
 * ```ts
 * const fPresentation = univerAPI.getActivePresentation();

 * const chartInfo = fSlide
 *   .newChart(univerAPI.Enum.ChartTypeString.Line)
 *   .setSource([['Month', 'Sales'], ['Jan', 120], ['Feb', 180]])

 * await fSlide.insertChart(chartInfo);

 * @example Board

 * const chartInfo = fBoard
 *   .newChart(univerAPI.Enum.ChartTypeString.Line)
 *   .setSource([['Month', 'Sales'], ['Jan', 120], ['Feb', 180]])
