Sample Demo – Icons/Floating Heads in a connection?

hello,
I want to to try and recreate the image attached, via your sample demo http://seventhqueen.com/themedemo/?product=kleo .

I know this is some sort of feature/tool/VC component, but I cannot seem to find it. Can you please how to advise to create the type of connection chain imagery showcased in your demo? I thought it might come in the demo data for my site, but i couldn’t find it any of the pages as they were.

Any points, or if you can provide me with an export of that sample, would be greatly appreciated.

Thank you!
