Your mission, should you choose to accept it, will be to build a data visualization web application that can analyze e-commerce data from a sample Shopify store stored in MongoDB. You will build an API layer that reads the data from the database and performs the necessary queries to manipulate data and serve it to the front end through a REST API. The front end should connect to your API and visualize the data using Chart.js or a similar JavaScript visualization library.
