/**
 * Convenience method for simple and default setup of zooming on an {@link XYChart} via a
 * {@link ChartZoomManager}. Wraps the chart in the components required to implement zooming. The
 * current implementation wraps the chart in a StackPane, which has the chart and a blue
 * translucent rectangle as children. Returns the top level of the created components.
 * <p>
 * If the chart already has a parent, that parent must be a {@link Pane}, and the chart is
 * replaced with the wrapping region, and the return value could be ignored. If the chart does
 * not have a parent, the same wrapping node is returned, which will need to be added to some
 * parent.
 * <p>
 * The chart's axes must both be a type of ValueAxis.
 * <p>
 * The wrapping logic does not seem to be perfect, in fact there is a special case to handle
 * {@link BorderPane}s. If it's not found to be reliable, then create the wrapping components
 * yourself (such as in the FXML), or setup zooming before adding it to a parent.
 *
 * @param mouseFilter EventHandler that consumes events that should not trigger a zoom action
 *
 * @return The top-level Region
