A 2D graphics item for rendering a tree as a dendrogram.
Draw a tree as a dendrogram The input tree's vertex data must contain at least two arrays. The first required array is a vtkStringArray called "node name". This array is used to label the leaf nodes of the tree. The second required array is a scalar array called "node weight". This array is used by vtkTreeLayoutStrategy to set any particular node's distance from the root of the tree.
The vtkNewickTreeReader automatically initializes both of these required arrays in its output tree.
