 * @summary XyDataSeries is a DataSeries for holding X, Y data in SciChart's 2D
 * {@link https://www.scichart.com/javascript-chart-features | JavaScript Charts}
 * @description
 * The XyDataSeries is primarily used with our {@link FastLineRenderableSeries | JavaScript Line Chart},
 * but can also be used by the {@link XyScatterRenderableSeries | JavaScript Scatter Chart} or
 * {@link FastMountainRenderableSeries | JavaScript Mountain/Area Chart} and {@link FastMountainRenderableSeries | JavaScript Column Chart}.
 *
 * To instantiate an {@link XyDataSeries}, use the following code:
 * ```ts
 * const xyDataSeries = new XyDataSeries(wasmContext);
 * xyDataSeries.append(1, 2); // Append a single x,y point
 * xyDataSeries.appendRange([3, 4], [3, 4]); // Append multiple x,y points (faster)
 * xyDataSeries.insert(0, 9, 10); // Insert a point at index 0
 * xyDataSeries.update(0, 11, 12); // Update a point at index 0
 * xyDataSeries.removeAt(0); // Remove a point at index 0
 * xyDataSeries.clear(); // Clear the dataseries
 * xyDataSeries.delete(); // Delete the dataseries and native (WebAssembly) memory
 * ```
 * @remarks
 * A DataSeries stores the data to render. This is independent from the {@link IRenderableSeries | RenderableSeries}
 * which defines how that data should be rendered.
 *
 * See derived types of {@link BaseDataSeries} to find out what data-series are available.
 * See derived types of {@link IRenderableSeries} to find out what 2D JavaScript Chart types are available.
