Answer 1

so I decided to implement it in a simple way with modules that I'm familiar with, Please do consider showing us your code in order to figure out what did gone wrong.

import matplotlib.pyplot as plt
import pandas as pd


if __name__=="__main__":
    df = pd.read_csv('50_million_primes_0.csv')
    
    X = df.Num
    Y = df.Prime

    print(Y)
    # Plot lines and/or markers to the Axes.
    plt.plot(X, Y)
    # Set the x axis label of the current axis.
    plt.xlabel('Num')
    # Set the y axis label of the current axis.
    plt.ylabel('Prime')
    # Set a title 
    plt.title('Draw a line.')
    # Display the figure.
    plt.show()
