GoJS - Genogram - Add padding around node in diagram

How can I create padding around node with link in diagram (as picture below) ?

I’ve created the invisible circle around node but It not the way I want. Any attributes of node or link can help on this ?

Adding a transparent object is certainly one way to do it. What is unsatisfactory with what you have done?

Alternatively, try setting Link | GoJS API and toShortLength. But for orthogonal links, the distance is limited by the …EndSegmentLength.

Thanks @walter
The issue with transparent object as picture below:

The black border is the transparent object but we still see the link.

Change the object that has portId set on it from the “Circle” Shape to your transparent Shape.
