Added the following new sample app yesterday. The app demonstrates linking customer referrals in a hierarchical manner. This means if customer A referred B , B referred C and C refereed D, then the app visually shows linkage between those customers as the screenshot below shows.
The sample app is based principally on the “Hierarchy Charts” sample app originally shared in this post thread.
A screenshot of the table view from the app that visually shows linked customer referrals.
