This example demonstrates a Node.js server that queries MongoDB collections and logs their contents to the console, primarily as a backend testing or debugging tool. The code uses the `mongo.Db` and `mongo.Server` APIs to connect to a local MongoDB instance on port 27017, then defines HTTP routes via a `get()` handler. For each route, it retrieves documents from specific collections—`some-collection` and `another-collection` (the latter with a limit of 10)—and prints each item using `sys.puts` and `sys.inspect`. The visualization aspect is absent; the example focuses on database interaction and response handling.
