We will create a new, simpler backend with just some READ routes (GET requests) as we will not need to update, create, or delete any cars. We will also insert a pretty hefty number of cars into our database – we need data to work with and we need a realistic number of entities in order to showcase the dashboard functionalities.

• Import the provided sample data from a Comma-Separated Values (CSV) document
• Create a new Python environment and install the required packages
• Scaffold our FastAPI application
• Create some MongoDB aggregations and map them into a FastAPI endpoint
