[USER (data scientist)]: That's cool. Now, I'd like to see a scatter plot of player rankings vs win/loss ratios. Please generate and display a scatter plot that compares player rankings with their win/loss ratios in the ATP tennis dataset.
My template of code snippet is:

---BEGIN CODE TEMPLATE---

import pandas as pd
import matplotlib.pyplot as plt
import seaborn as sns
from decision_company import read_csv_file,

# please import the necessary private functions from decision_company first

atp_tennis = read_csv_file('atp_tennis.csv')

fig2, ax2 = create_subplots()

# YOUR SOLUTION BEGIN:
<code1>
[COMPLETE YOUR CODE] 
</code1>
# YOUR SOLUTION END

# save data
save_plot('./pred_result/scatter_chart.png')
show_plots()

---END CODE TEMPLATE---

[YOU (AI assistant)]: Sure thing! Here's the code to create a scatter plot using matplotlib:

# please import the necessary private functions from decision_company first

atp_tennis = read_csv_file('atp_tennis.csv')

fig2, ax2 = create_subplots()
