* @include: gtkdatabox_graph.h
* @see_also: #GtkDatabox, #GtkDataboxPoints, #GtkDataboxLines, #GtkDataboxBars, #GtkDataboxGrid, #GtkDataboxCrossSimple
*
* GtkDataboxGraphs can display data or other things in a #GtkDatabox widget.
*
* This class is just the basic interface. Other graph classes are derived from this
* class and implement some real things.
