• Two image fitting modes: 'crop' and 'stretch'
• Simple and intuitive API
• Customizable output size, background color, and labels

Example Ouptut

This example shows cities sized by time spent:

Usage

from mosaicmap import MosaicMap

# Initialize mosaicmap creator
mosaicmap = MosaicMap()

# Prepare your data
data = {
    'labels': ['Product A', 'Product B', 'Product C'],
    'values': [500, 300, 200],  # Size values for each rectangle
    'image_paths': ['path/to/image1.jpg', 'path/to/image2.jpg', 'path/to/image3.jpg']
}

# Create the mosaicmap
mosaicmap.create(
    data=data,
    output_path='output_mosaicmap.png',
    image_mode='crop',  # or 'stretch'
    width=800,
    height=600,
    background_color=(255, 255, 255),  # white
    show_labels=True,  # Enable labels, False by default
    font_size=16  # Optionally adjust font size
)
