Attractor point that creates a "bulge" instead of a "peak"

I'm trying to set up a standard attractor point definition:
A grid with boxes in each cell where the size of the boxes depends on the distance to an attractor point.

However, I'm looking for a somewhat different effect than what I get.

I'd like to create a "bulge" more than a "peak" in the box grid. Any ideas on how to do this? I have a fealing this could be done with an expression, but my math knowledge is not at it's peak (or bulge) at the moment.

I hope this illustrates what I'm aiming for:

This (an exponential form) is what I'm getting right now:


A peak that is, and the shape I'm looking for is more like a bulge.
Could this be achieved with some sort of expression? I want the height of the boxes to increase the closer they are to the attractor point, but when the come within a certain distance the increasing movement will decline.

Or is there a way to set this up without using an expression/function?

Thanks! I'll sit down tomorrow and try to figure it out,

Yes, use the graph mapper component. This way you have more control over the shape of your bulge:
