Architecture and explanation

This project uses the SignalR library to configure a server-sent event hub.

The SignalR Hubs API enables connected clients to call methods on the server. SignalR takes care of everything required to make real-time client-to-server and server-to-client communication possible. In this prototype, a server-sent event hub has been implemented.

Here, the client initiates the connection to the server, which is kept open until a cancel request is sent. When new data becomes available on the channel, the response is immediately sent to the client.

The client plots a real-time chart for two different people, and keeps the visualization for the latest 30 records.
