44 * Modified {@link StackedAreaRenderer}.
45 *
46 * <ol>
47 * <li>Built-in support for {@link #generateToolTip(CategoryDataset, int, int) tooltip}
48 * and {@link #generateURL(CategoryDataset, int, int) hyperlinks} for clickable map.
49 * <li>Clickable map hit test is modified so that the entire area is clickable,
50 * not just the small area around each data point.
51 * <li>Rendering algorithm is modified so that
52 * {@link #getItemPaint(int, int) different color on the same data series}
53 * will look more natural.
