Matplotlib - 3D Plotting

Why does this code raise an error?

from mpl_toolkits.mplot3d import Axes3D
import matplotlib.pyplot as plt
fig = plt.figure()
ax = fig.add_subplot(111, projection='3d')
ax.scatter([1,2], [3,4])
plt.show()

AAxes3D import is incorrect.

Bscatter requires three coordinate arrays for 3D plots.

Cplt.figure() must include projection='3d'.

Dplt.show() is missing.

Step-by-Step Solution

Solution:

Step 1: Check scatter arguments for 3D
3D scatter requires x, y, and z coordinate arrays; only two are given.
Step 2: Verify other code parts
Axes3D import is correct, figure creation is fine, and plt.show() is present.
Final Answer:
scatter requires three coordinate arrays for 3D plots. -> Option B
Quick Check:
3D scatter needs x,y,z arrays = B [OK]

Quick Trick: 3D scatter needs three coordinate lists: x, y, and z [OK]

Common Mistakes:

Providing only two coordinate arrays for 3D scatter
Thinking Axes3D import is wrong
Assuming plt.show() is missing
