/**
 * Creates a bubble chart with default settings. The chart is composed of an {@link XYPlot}, with a {@link NumberAxis} for the
 * domain axis, a {@link NumberAxis} for the range axis, and an {@link XYBubbleRenderer} to draw the data items.
 * /*from www. ja  va2s .  com*/
 * This method is copied from
 * {@link org.jfree.chart.ChartFactory#createBubbleChart(String, String, String, XYZDataset, PlotOrientation, boolean, boolean, boolean)}
 * 
 * @param title the chart title (<code>null</code> permitted).
 * @param xAxisLabel a label for the X-axis (<code>null</code> permitted).
