How to correctly scale in Yandex API?

Question

Yandex

An example from Yandex
Here is an example of a heat map. When approaching, thermal points begin to appear separately from each other. How to do this (and is it possible at all) so that the point has a radius of "action" by analogy with Circle (I tried to do it directly with the help of it, but there is a problem that when a large number of circles are superimposed, the map itself is not visible. If there is a way get rid of it, then it will also be one of the options for solving the problem)?
