Matplotlib - Real-World Visualization Patterns

APlot line, use plt.scatter to highlight max, no annotation needed

BPlot line, use plt.fill_between to highlight max point, add annotation without arrowprops

CFind max y value index, plot line, use plt.annotate with xy at max point and xytext offset, add arrowprops

DPlot line, add annotation at (0,0), use arrowprops with empty dict

Step-by-Step Solution

Solution:

Step 1: Identify max point and plot line
Find index of max y, plot the line to visualize data.
Step 2: Use annotate with correct parameters
Use plt.annotate with xy at max point, xytext offset for label, and arrowprops to draw arrow.
Final Answer:
Find max y value index, plot line, use plt.annotate with xy at max point and xytext offset, add arrowprops -> Option C
Quick Check:
Highlight max with annotate and arrow = Find max y value index, plot line, use plt.annotate with xy at max point and xytext offset, add arrowprops [OK]

Quick Trick: Annotate max point with arrowprops for clear highlight [OK]
