For the following code, add a trendline and a line for the mean throughout the plot:

import matplotlib.pyplot as plt
import pandas as pd


# Convert the "aangebodensinds" column to datetime format
df['dates'] = pd.to_datetime(df['dates'], format='%d-%m-%Y')

# Create the scatter plot
plt.scatter(df['dates'], df['m2_prijs'])

# Set the x-axis label
plt.xlabel('Date')

# Set the y-axis label
plt.ylabel('m2_prijs')

# Rotate the x-axis tick labels for better visibility
plt.xticks(rotation=45)

# Show the plot
plt.show()
