Function traitgraph::algo::predefined_graphs::create_binary_tree

pub fn create_binary_tree<Graph: DynamicGraph>(
    graph: &mut Graph, 
    depth: i32
) -> Option<Graph::NodeIndex> where
    Graph::NodeData: Default,
    Graph::EdgeData: Default, 

Adds a binary tree to the given graph. The first added node is the root of the tree. A negative depth adds no nodes to the graph, a depth of 0 just the root, a depth of 1 the root an its children, and so on.
