Simple app to validate server sent events (SSE).
- The client creates a EventSource with an endpoint provided by a node.js server.
- This endpoint sets the socket timeout to infinity, and broadcasts the server's CPU usage at a fixed interval to the socket
- The client updates the D3 chart when it receives a new message.
- Have client update chart based on local clock (tick()), indepently from data sent by server
- Smoothen transitions
