We can use Matplotlib, NumPy, and the wave module to plot waveforms of WAV files.

import matplotlib.pyplot as plt
import numpy as np
import wave
import sys

wav=wave.open('chicken.wav', 'r')
#We only want to use mono files
if wav.getnchannels()==2:
  print('Stereo files are unsupported. Use mono files.')
  sys.exit(0) #Terminates program

raw=wav.readframes(-1) #This reads all frames, returns them in byte form
raw=np.frombuffer(raw, dtype='int16') #Converts bytes to integers
sample_rate=wav.getframerate()
time_=np.linspace(0, len(raw)/sample_rate, num=len(raw))

plt.title("Waveform of Chicken")
plt.plot(time_, raw, color="blue") #Plot time and amplitude
plt.xlabel("Time (s)")
plt.ylabel("Amplitude")
plt.tight_layout()
plt.savefig('chicken.png')
plt.show()

This should result in something like this:
