Water usage

Generating a visual representation of water usage using pie charts.

Importing libraries and packages

# Mathematical operations and data manipulation
import pandas as pd

# Plotting
import matplotlib.pyplot as plt

# Warnings
import warnings

warnings.filterwarnings("ignore")

%matplotlib inline

Set paths

# Path to datasets directory
data_path = "./datasets"
# Path to assets directory (for saving results to)
assets_path = "./assets"

Loading dataset

dataset = pd.read_csv(f"{data_path}/water_usage.csv")

Exploring dataset

Shape of the dataset:  (6, 3)

	Unnamed: 0	Usage	Percentage
0	0	Leak	12
1	1	Clothes Washer	17
2	2	Faucet	19
3	3	Shower	20

Visualisation

# Create figure
plt.figure(figsize=(6, 6), dpi=300)
# Create pie plot
plt.pie(
    "Percentage",
    explode=(0, 0, 0.1, 0, 0, 0),
    labels="Usage",
    data=dataset,
    autopct="%.0f%%",
)
# Add title
plt.title("Water usage")
# Show plot
plt.show()
