/**
* The PolarMouseWheelZoomModifier provides Mouse wheel zooming behavior on a 2D {@link SciChartPolarSurface}
* within SciChart - High Performance {@link https://www.scichart.com/javascript-chart-features | JavaScript Charts}
* @remarks
*
* To apply the PolarMouseWheelZoomModifier to a {@link SciChartPolarSurface} and add Mouse-wheel zoom behavior,
* use the following code:
*
* ```ts
* const sciChartSurface: SciChartPolarSurface;
* sciChartSurface.chartModifiers.add(new PolarMouseWheelZoomModifier());
* ```
*
* The speed of mouse-wheel zoom can be modified via the {@link PolarMouseWheelZoomModifier.growFactor} property.
