Visualization of Abstract Syntax Tree

[constantin01]

Hi

I am working on parser for Russian and I would like to have visualization of abstract syntax tree. I want to see it in following way:

I have my tree class:

class Node:
	def __init__(self, word=None, tag=None, grammemes=None, leaf=False):
		self.word = word;
		self.tag = tag;
		self.grammemes = grammemes;
		self.leaf = leaf;

		self.l = None;
		self.r = None;
		self.p = None;

class Tree:
	def __init__(self, grammar):
		self.grammar = grammar;
		self.root = None;
		self.nodes = list();

I build it from given sentence and then I write:

my_tree.draw()

And here is pop-up window (as tkinter) with my tree. Like this:

How I can implement it?
