how to draw axes passing through the origin in a 3D plot using matplotlib

I want to create a 3d plot like the following, such that axes pass through the origin with ticks on them.

PS: I could do that for 2D plots using matplotlib (the following figure). I searched a lot to do the same for 3D plots but I did not find any info.

If you want to restrict yourself to just matplotlib then we can use quiver3d plot as shown below. But the results may not be very visually appealing. You can see here how to add 3D text annotations.

from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
import numpy as np

fig = plt.figure()
ax = fig.add_subplot(111,projection='3d')
ax.set_xlim(0,2)
ax.set_ylim(0,2)
ax.set_zlim(0,2)
ax.view_init(elev=20., azim=32)

# Make a 3D quiver plot
x, y, z = np.zeros((3,3))
u, v, w = np.array([[1,1,0],[1,0,1],[0,1,1]])

ax.quiver(x,y,z,u,v,w,arrow_length_ratio=0.1)
plt.show()
