generate with pandas and matlab a function that reads a csv called propines and returns a graph with columns "Total_ticket" and "Propina". And draw a line with pearson method

`import pandas as pd import matplotlib.pyplot as plt import numpy as np def read_csv(csv): return pd.read_csv(csv) def draw_csv(csv, x, y): propinas = read_csv(csv) plt.scatter(x, y) plt.show() return def draw_csv_with_pearson(csv, x, y): propinas = read_csv(csv) plt.scatter(x, y) plt.plot(np.unique(x), np.poly1d(np.polyfit(x, y, 1))(np.unique(x))) plt.show() return`
