Can you provide an online sample where the issue is reproduced?

I've tested the new 3.x version for 500 level tree and it was working as expected, previous version was inefficient for large level trees.

Appreciate the prompt response!

I have tested with the latest 3.x version(3.1.1) and it is working as expected but observed that Pagination is not working with the 3.1.1 version with angular15.

The issue is reproducible in the below link: https://stackblitz.com/edit/angular-ivy-x5qr97?file=package.json,src%2Fapp%2Fapp.component.ts,src%2Fapp%2Fcomponents%2Fd3-org-chart%2Fd3-org-chart.component.html,src%2Fapp%2Fcomponents%2Fd3-org-chart%2Fd3-org-chart.component.ts,src%2Fapp%2Fapp.component.html,src%2Fapp%2Fapp.module.ts,src%2Fapp%2Fcomponents%2Fphoto-gallery%2Fphoto-gallery.component.ts
