Creates an area mark using the specified horizontal and vertical positions.

## Declaration

```swift
nonisolated init<X, Y>(x: PlottableValue<X>, y: PlottableValue<Y>, stacking: MarkStackingMethod = .standard) where X : Plottable, Y : Plottable
```

## Parameters

- `x`: The horizontal position for the mark.
- `y`: The vertical position for the mark.
- `stacking`: The way in which the chart stacks area regions. The default is doc://com.apple.Charts/documentation/Charts/MarkStackingMethod/standard.
