Documentation : https://sbcode.net/typescript/observer/#observer-use-case

There is an external process called a DataController, and a client process that holds a DataModel and multiple DataViews that are a Pie graph, Bar graph and Table view.

Note that this example runs in a single process, but imagine that the DataController is actually an external process running on a different server.

The DataModel subscribes to the DataController and the DataViews subscribe to the DataModel.

The client sets up the various views with a subscription to the DataModel.

The hypothetical external DataController then updates the external data, and the data then propagates through the layers to the views.
