What is wrong with this code?

import matplotlib.pyplot as plt
plt.plot([1,2,3], [3,2,1])
plt.annotate('Low', xy=(2,2), xytext=(3,1), arrowprops='->')

Barrowprops should be a dictionary, not a string

CMissing plt.show() call

DNo error, code runs correctly

Quick Check:
arrowprops must be dict = arrowprops should be a dictionary, not a string [OK]

Quick Trick: arrowprops needs dict like dict(arrowstyle='->') [OK]
