<｜begin▁of▁sentence｜>### Instruction:
Given a directed graph with edges [(0, 1), (1, 2), (1, 3), (2, 4), (2, 5), (0, 'A'), (3, 'B'), (3, 'C'), ('C', 'D'), ('C', 'E')], how can one use NetworkX's `generate_network_text` method to generate a visual textual representation of the graph, suitable for displaying in console or text environment?
### Response:
import networkx as nx

# Create a directed graph
G = nx.DiGraph()

# Add nodes and edges forming a tree with some additional edges
G.add_edge(0, 1)
G.add_edge(1, 2)
G.add_edge(1, 3)
G.add_edge(2, 4)
G.add_edge(2, 5)
G.add_edge(0, 'A')
G.add_edge(3, 'B')
G.add_edge(3, 'C')
G.add_edge('C', 'D')
G.add_edge('C', 'E')

# Use generate_network_text to produce a visual representation of the graph
for line in nx.generate_network_text(G):
    print(line)
