This helper script will give a function to plot the given vectors. One can input the 2-tuple vectors in an array and get the plot of them.
def plot_vectors(vectors, title=None):
import numpy as np
from matplotlib import pyplot as plt
# Initiate the plot
fig, ax = plt.subplots(figsize = (5,5))
# Draw each vector as quiver plot
for x_cor, y_cor in vectors:
ax.quiver(0,0,x_cor,y_cor,
scale=1,angles='xy',
