Learn how to generate complex, interconnected mock datasets for Python development and testing in this 21-minute conference talk from PyBay 2023. Discover a solution that bridges the gap between simple mock data generators and synthetic data services by using a JSON configuration file with the graph-data-generator PyPi package. Master techniques for creating realistic, interdependent fake datasets without relying on error-prone custom scripts or requiring real data for anonymization. Delivered at the single-track regional Python conference for the San Francisco Bay Area, this presentation offers practical insights for both beginners and experienced developers working with mock data generation.
