"""
Very simple example demonstrating RemoteGraphicsView.
This allows graphics to be rendered in a child process and displayed in the
parent, which can improve CPU usage on multi-core processors.

## Create the widget
v = RemoteGraphicsView(debug=False) # setting debug=True causes both processes to print information
# about interprocess communication

## v.pg is a proxy to the remote process' pyqtgraph module. All attribute
## requests and function calls made with this object are forwarded to the
## remote process and executed there. See pyqtgraph.multiprocess.remoteproxy
