webagg backend example?

Gang:

Are there any webagg examples you could point me to? With webagg configured as the backend in my matplotlibrc and the following code, my browser opens after the call to show() with a webpage “MPL | WebAgg current figures” and a link to “Figure 1”, but I don’t get any plot, before or after clicking the link …

import matplotlib.pyplot as pyplot
import numpy
pyplot.plot(numpy.random.random(100))

[<matplotlib.lines.Line2D object at 0x103398f90>]

pyplot.show()

Many thanks,
Tim
