Visualisation of interaction for the logistic regression

In this post we are plotting an interaction for a logistic regression. Interaction per se is a concept difficult to grasp; for a GLM it may be even more difficult especially for continuous variables’ interaction. Plotting helps to better or more easy grasp what a model tries to tell us.
