There is a case when one needs to make a structural representation of data which resides in a single table, with records referenced to one another. This is not difficult to make, but sometimes people just doesn't have time.

I had small table with linked records, that I had to represent structurally. Table was something like:

where record Id 2, links to record Id 1,  by third field.

I have found a component on the internet from Singapore Flex Usergroup, but it didn't worked for my case as I needed to.
So I took the liberty to alter the component and share it.

D-Click developers already have this component set in flex_library.

You may download small Flex3 demo application along with the component from following link:
