df.plot(..., kind="area").

Goal

Draw this kind four ways.

df = pd.DataFrame({
    "city": ["Nairobi", "Mombasa", "Kisumu", "Nakuru", "Eldoret"],
    "units": [21, 15, 15, 18, 12],
    "shillings": [2100, 1500, 1480, 1750, 1190],
})
df.plot(x="city", y="units", kind="area")
plt.title("area")
plt.show()

df = pd.DataFrame({
    "mango": [12, 7, 11],
    "soda": [9, 8, 4],
}, index=["Nairobi", "Mombasa", "Kisumu"])
df.plot(kind="area")
plt.title("area")
plt.show()
