[Python] How do I load data from a CSV file using this code? Or other methods?

I'm trying to get this code to work by using Only CSV data from a CSV file (prices.csv below) is there a way to remove the ABCDE n_bars value and replace it with a CSV version for this code? If anyone has anyway of doing this please demonstrate using comment indicator (#) so I can learn, thanks.

import numpy as np
import matplotlib.pyplot as plt
from matplotlib.widgets import Slider
from itertools import product

n_bars = 100
n_shown = 10

names = ["".join(t) for t in product("ABCDE", "ABCDE", "ABCDE")][:n_bars]
np.random.seed(20250502)
values = np.random.randint(1, 11, n_bars)

fig, ax_d = plt.subplot_mosaic("a" * 7 + "b")
ax_d["a"].barh(names, values)
ax_d["a"].axis([-0.2, 10.2, -0.5, n_shown-0.5])
ax_d["a"].invert_yaxis()

spos = Slider(ax_d["b"], "", -0.5, n_bars-n_shown-0.5, orientation="vertical")
def update(val):
pos = spos.val
ax_d["a"].axis([-0.2, 10.2, pos+n_shown, pos])
fig.canvas.draw_idle()
spos.on_changed(update)

plt.show()
