 /**
  * Class containing the basic options for renderers.
  *
+ * Renderer options are used to define the general appearance of charts beside
+ * the palettes. The renderer transforms chart primitives (like the legend, or
+ * one pie slice) into image primitives, which are then rendered by the
+ * drivers. The way this transformation is done, and which effects are also
+ * rendered is specified by the values in this option class. 
+ *
+ * The example below shows some basic bar rendering options, which are
+ * available in all renderers. You mya want to check the tutorial sections
+ * about the renderer, which show example output for more renderer options.
+ *

+ * For additional options, which are special to some chart type you may
+ * also want to check the option classes for the repective chart type you

+ * - ezcGraphLineChartOptions
+ * - ezcGraphPieChartOptions
+ * - ezcGraphRadarChartOptions

+ * There may be additional options dependant on the renderer you are using.
