How to use Python to create interactive plots under Orange?

I would like to use Orange to create a 3D scatterplot but apparently this feature has not yet been implemented (although it was recently requested: see here).

I started playing with the Python script "widget".

I managed to create a plot that I could later save to a png image:

from Orange.preprocess import DomainDiscretizer
discretizer = DomainDiscretizer()
d_test = discretizer(in_data)
print(d_test[1].values)
import matplotlib.pyplot as plt

plt.scatter(d_test[1].values,d_test[2].values)

plt.savefig('testplot.png')

However, I cannot create an interactive plot. Under Spyder or Jupyter, I would simply type %matplotlib to use the Qt5Agg backend, but doing so in the Orange console returns the following error:

SyntaxError: invalid syntax

How can I create an interactive plot using the Python widget in Orange?
