How can I visualize text data using NLTK?

You can use NLTK along with libraries like Matplotlib and Seaborn to visualize text data. Would you like a code example?

Yes, please provide a code example for visualizing word frequencies.

Sure! Here's a simple example:

import nltk
from nltk.probability import FreqDist
import matplotlib.pyplot as plt

# Sample text
text = "This is a sample text with several words. This text is for visualization."

# Tokenize the text
words = nltk.word_tokenize(text)

# Calculate frequency distribution
freq_dist = FreqDist(words)

# Plot the frequency distribution
freq_dist.plot(30, cumulative=False)
plt.show()

What if I want to visualize bigrams instead?

You can use NLTK's bigrams function to visualize bigrams. Here's how:

from nltk import bigrams
from collections import Counter

# Create bigrams
bigrams_list = list(bigrams(words))

# Count bigrams
bigram_freq = Counter(bigrams_list)

# Plotting can be done similarly using Matplotlib.
