Matplotlib - Export and Publication Quality

Why does this code produce a blurry saved image?

fig = plt.figure(figsize=(8,6))
plt.plot([1,2,3])
fig.savefig('plot.png')

Assuming default DPI is 100.

ABecause figsize is too small

BBecause the DPI is too low for the large figure size

CBecause plt.plot() needs more data points

DBecause savefig() was called without a filename

Step-by-Step Solution

Solution:

Step 1: Understand default DPI effect
Default DPI is 100, so large figure size (8x6 inches) results in 800x600 pixels.
Step 2: Relate DPI to image sharpness
800x600 pixels may be low resolution for large images, causing blurriness.
Final Answer:
Because the DPI is too low for the large figure size -> Option B
Quick Check:
Low DPI + large size = blurry image [OK]

Quick Trick: Increase dpi for large figures to avoid blur [OK]
