How do I plot the first two columns from a csv file?

graph

I have a csv file that contains the following: the date a tweet is published, the sentiment value (0=negative and 1=positive), and then the tweet in the third column, all seperated by commas.

I need to plot the date on the x-axis and the sentiment value on the y-axis to see the change of tweets sentiment as time passes. the file looks like this

Date,SA,Tweet,

What I have tried:

I have searched many sites and run many codes but nothing seems to work.
I thought of using time series but i dont know the correct way
A sample code i used(which i am sure is wrong):

import pandas as pd
import plot_utils as pu
df = pd.read_csv('SA.csv', index_col=0)
pu.plot_timeseries(df['SA'], ylabel='Unit: %', title='Sentiment anaylsis variation')

I get this error:

ValueError: Unknown string format

and an empty graph
