import pandas as pd
import matplotlib.pyplot asplt

df = pd.read_csv("path of csv file")
df.head()

plt.plot(df['x'], df['y'], 'o')
plt.show()

Also, the pandas.DataFrame class has the pandas.DataFrame.plot —pandas 1.5.2 documentation method, which is used as follows:

import pandas as pd
import matplotlib.pyplot asplt

df = pd.read_csv("path of csv file")
df.head()

df.plot(x='x', y='y',kind='scatter',marker='o')
plt.show()
