I'm trying to make a program using PyQt5 and pyqtgraph, however, I keep running into this error:

ImportError: cannot import name 'QGraphWidget'

I used QtDesigner to make a form and promoted a QGraphicsWidget. I know I did it correctly (I've done it at least 10 times to try and resolve the issue), but the error persists.
I'm using Windows 7, Anaconda, and PyCharm, but I tried running the code in other environments and still got the error.
In the documentation it implies that the promoted name can be anything, however, this seems to be untrue (at least at the moment).

Under “Promoted class name”, enter the class name you wish to use (“PlotWidget”, “GraphicsLayoutWidget”, etc).

After re-doing my QGraphicsWidget for the 6th time, I decided to name it one of the example names in the tutorial, which seems to have solved the problem.
In other words name your widget and promoted widget "PlotWidget", "ImageView", "GraphicsLayoutView", or "GraphicsView". (Please keep in mind I have only tested "PlotWidget".)
pyqtgraph QGraphicsWidget import error
