Request

I need an entirely synthetic retail sales dataset for testing a sales forecasting demo. Please provide 12 months of daily sales for 10 fictional stores and 20 fictional products, covering January through December 2025. Include date, fictional store ID, fictional product ID, units sold, unit price in USD, and promotion flag. Deliver CSV files with a data dictionary and a short explanation of how the data was generated. Include weekly patterns and seasonal variation. Do not include real people, real businesses, personal information, or contact details. The data must be licensed for use and modification in a demo.
