2. Analyze the data for trends, seasonality, and fluctuations relevant to the product.
3. Identify key factors influencing purchasing behavior (e.g., price changes, promotions, external events).
4. Provide insights that can directly inform demand forecasting and sales strategy.
5. Suggest additional data sources that could enhance the analysis.

Output format A structured analysis with sections: trend summary, seasonal patterns, key influencing factors, implications for forecasting, and recommended data sources. Use bullet points and, if helpful, simple tables.
