Matplotlib - Performance and Large Data

What will be the output of this code snippet?

import matplotlib
matplotlib.use('Agg')
import matplotlib.pyplot as plt
plt.plot([1, 2, 3])
plt.savefig('plot.png')
print('Done')

AA plot window opens and 'Done' is printed

BError because Agg backend does not support savefig

C'Done' is printed and 'plot.png' file is saved without opening a window

DNothing happens because Agg disables plotting

Step-by-Step Solution

Solution:

Step 1: Analyze backend behavior
Agg backend does not open GUI windows but supports saving plots to files.
Step 2: Trace code execution
The plot is created, saved as 'plot.png', and 'Done' is printed. No window opens.
Final Answer:
'Done' is printed and 'plot.png' file is saved without opening a window -> Option C
Quick Check:
Agg saves files, no GUI window [OK]

Quick Trick: Agg backend saves files silently, no GUI [OK]
