Baby Icon Example

import numpy as np
import matplotlib.pyplot as plt
from demoviz import DemoScatter

# Create sample baby health data
ages = [0, 6, 12, 18, 24]  # Age in months
weights = [3.5, 7.0, 9.5, 11.0, 12.5]  # Weight in kg

# Create the plot
fig, ax = plt.subplots(figsize=(8, 6))

# Initialize DemoScatter with baby icons
demo = DemoScatter(icon_size=40, zoom=0.4)

# Plot babies with baby icons
demo.plot(ax, ages, weights, icon_type='baby', colors='lightblue')

# Customize the plot
ax.set_xlabel('Age (months)')
ax.set_ylabel('Weight (kg)')
ax.set_title('Baby Growth Chart')
ax.grid(True, alpha=0.3)

plt.tight_layout()
plt.show()
