The Diagram represents the diagram being exchanged. The initialView attributes can be used to specify an initial view with the x,y coordinates of the diagonal points. The coordinate system is a standard Cartesian coordinate system and the orientation attribute defines a positive or negative orientation. A positive orientation gives standard ‘right-hand’ orientation, with negative orientation indicating a ‘left-hand’ orientation. For 2D diagrams, a positive orientation will result in X values increasing from left to right and Y values increasing from bottom to top. A negative orientation gives the ‘left-hand’ orientation (favoured by computer graphics displays) with X values increasing from left to right and Y values increasing from top to bottom.The Diagram represents the diagram being exchanged.
