This example shows a series of MongoDB shell commands that demonstrate basic CRUD operations and query patterns against a restaurant dataset. The code performs actions like finding all documents, sorting and limiting results, retrieving documents by `_id` or field values, counting records, deleting single documents, and updating either one or many documents using `updateOne` and `update` with the `$set` operator. It also illustrates how to obtain an `ObjectId` from a query result and use it for subsequent operations. The visualization presents these commands as a linear drill sequence, making the MongoDB query syntax and workflow explicit.
