Wgraph:Demo vertical order

• In hierarchical layouts you can enforce the level on which a node is placed
• level 0 is the top most level
• You can even "reverse edges", see A4-B4
• See also Wgraph:Demo horizontal_order

 edge D2 C2 {}
 node A2 { vertical_order 1 }
 node D2 { vertical_order 0 }

 node A3 { vertical_order 3 }

 node A4 { vertical_order 2 }
 node B4 { vertical_order 1 }
 edge A4 B4 {}
