+/**
+ * Plot area used for map plots.
+ *
+ * A map plot is a chart that displays a map (fx. a world map) in the form of .
+ * png file. The maps must be located in the /Images/Maps folder and a
+ * corresponding .txt files mush also exist in this location where named
+ * locations are mapped to an (x, y) coordinate of the map picture (this text
+ * file is tab separated with 'Name' 'X' 'Y' values, fx 'Denmark 378 223'). The
+ * x-values in the dataset are then the named locations (fx 'Denmark') and the
+ * y-values are then the data to plot. Currently the best (if not only) use is
+ * to combine a map plot area with a {@link Image_Graph_Plot_Dot} using {@link
+ * Image_Graph_Marker_PercentageCircle} as marker.
