The sklearn.set_config(display='diagram') feature highlighted here needs more prominence. At least, it should be easy to find it when googling scikit-learn diagram display. It isn't. scikit-learn display=diagram is much the same, and scikit-learn "display=diagram" is on the mark but the results are not easy to parse as being relevant.

We probably need an example, or a user guide page, showing how different estimators are diagrammed, and perhaps also instructing users to use IPython.display's display function when needed.
