type arrow_style =
| Directed | (* edges are directed and an arrow is drawn at the end of an edge *) |
| Undirected | (* edges are undirected and no arrow is drawn *) |
The style of arrows between nodes
type edge_style =
There are several styles available for edges
val node :
?ls:Num.t ->
?cs:Num.t ->

node label children
creates a node with label label
and a list of children children
. Default arrow_style is Directed
. Default edge_style is Straight
.
ls
(level sep): vertical distance between levels. The default value is 1.0. A negative value draws the tree upward.cs
(children sep): horizontal distance between siblings. The default value is 0.2. Optional arguments are the same as inleaf
.

Similar to node
but with labels on edges. Labels are taken into account only when edge_style
is Straight
.

bin label l r
creates a binary node with label label
and children l
and r
. Optional arguments are the same as in leaf
