Help me plot a forecast

To visualize the forecasts alongside the original demand data, create a graph with years on the x-axis and demand values, a 3-year moving average forecast, and a weighted 3-year moving average forecast on the y-axis. This graph will help you and the executive team understand how these different forecasting methods compare to the actual demand data over the specified period. Make sure to label the axes and the lines for clarity.

In summary, by using both a simple 3-year moving average and a weighted 3-year moving average, you can make informed forecasts for product demand in the coming years, which will be essential for planning production material orders and managing the supply chain effectively.
