• Direction – determines how the drawing is oriented in the 2D drawing space. By default it is oriented from Top to Bottom. Other possible orientations are: from Bottom to Top, from Left to Right and from Right to Left.


• LayerSpacing and VertexSpacing – determine the spacing between the layers and the vertices.


• EdgeRouting – determines whether to use polylines or only horizontal and vertical line segments to draw the edges.

• InPlugSpacing and OutPlugSpacing – determine the spacing between the plugs of a node. You can set a fixed amount of spacing or a proportional spacing, which means that the plugs are distributed along the whole side of the node.


• LayerAlignment and NodeAlignment – specifies how the vertices are aligned within the layer vertically and horizontally respectively. The possible values are Near, Center and Far. For example if the direction is TopToBottom, then Near means that the vertices are aligned to the top of the layer, Center – to the center of the layer and Far – to the Bottom of the layer.

• NodeRank - specifies the node ranking policy used by the layout. It can be:
• TopMost - all nodes without incoming edges are assigned to the topmost layer
• Gravity - layer distribution is done in such a way that the total length of all edges is minimized
• Optimal - similar to the topmost, but after the initial assignment all nodes fall downwards as much as possible
