Who can explain how supercluster works?

Question

JavaScript

Hello! Who can explain how supercluster works ?
I don’t quite understand how the array of points objects should look like and how to get clusters as a result.
I see the trees object is created there, but it is empty for me.
I would be very grateful for your help!

It is also written there - there must be a geojson with a filling in the form of dots.
