如何在Python/Jupyter Notebook中漂亮地打印或可视化'CoreNLP_pb2.ParseTree‘类的对象？

import pprint
from graphviz import Digraph

def visualize_parse_tree(parse_tree):
    dot = Digraph()
    dot.node('0', 'ROOT')
    
    def add_nodes(node):
        for i, child in enumerate(node.child):
            dot.node(str(child.index), child.word)
            dot.edge(str(node.index), str(child.index), label=child.dep)
            add_nodes(child)
    
    add_nodes(parse_tree.root)
    dot.render('parse_tree', format='png', view=True)

pprint.pprint(parse_tree)
