 In this example, we'll create a pipeline that fetches recent stock data using the [quantmod package](https://github.com/joshuaulrich/quantmod), performs time series analysis, and forecasts future stock prices using the [Prophet model](https://github.com/facebook/prophet). We first design the `stock_data_block`, containing a field to select the stock items and generate the data. The `prophet_forecast_block` does all the modeling part.
