Note that GraphicsWindow is deprecated in favor of GraphicsLayoutWidget, but in any case, you'll need to make sure you show the window. In addition, unless you're running this code in an interactive environment (e.g. the Python/IPython REPL or running a script with the -i flag), you also need to run the Qt event loop at the end. Does the following work?
