| Description: |
layout_downfactor, layout_upfactor, layout_nearfactor The layout algorithm partitions the set of edges into edges pointing upward, edges pointing downward, and edges pointing
sidewards. The last type of edges is also called near edges. If the layout_downfactor is large compared to the layout_upfactor and the layout_nearfactor, then the positions of the nodes is mainly determined by the edges pointing downwards. If the layout_upfactor is large compared to the layout_downfactor and the layout_nearfactor, then the positions of the nodes is mainly determined by the edges pointing upwards. If the layout_nearfactor is large, then the positions of the nodes is mainly determined by the edges pointing sidewards. These attributes have no
effect, if the method for downward laid out trees is used.
