Request

I need a fully synthetic retail transactions dataset for testing a demo analytics dashboard. Please provide 10,000 fictional transactions with transaction date, fictional product ID, product category, quantity, unit price in USD, discount, and fictional store region. CSV or JSON is preferred. Include a data dictionary and describe how the synthetic records were generated. Do not include real people, customer identifiers, contact details, or real transaction records. The dataset will be used only to test charts, filters, and aggregate sales calculations.
