meat = pd.read_csv("meat.csv")
print(meat.head(5))

Summarizing and plotting multiple time series

import matplotlib.pyplot as plt
plt.style.use('fivethirtyeight')
ax = df.plot(figsize=(12, 4), fontsize=14)

plt.show()

The Meat production dataset

Area charts

import matplotlib.pyplot as plt
plt.style.use('fivethirtyeight')
ax = df.plot.area(figsize=(12, 4), fontsize=14)

plt.show()

The Meat production dataset as an Area Chart

Let's practice!
