SSRS 2008 - Create a chart of a directed graph to visualise ETL jobs

Question

I can't find anything that hints towards native support for charting graph data structures (otherwise known as "network maps" by some), and in my case, a directed graph. I'm wanting to create a visualisation of our ETL dependency chain at work to show the steps that each different 'job' is reliant on before being able to proceed.

Questions:

• Has anybody been able to 'simulate\hack\workaround' this lack of out-of-the-box functionality in SSRS?
• Any ideas on how to possibly achieve this if no-one has thought of doing this before?

EDIT - 2014-10-30
Two years and no answer so I've accepted the most promising advice on a workaround to get what is needed, as no direct functionality has been found.

Answer 1

From left field: You could wrap an SSIS package around your "ETL jobs". The SSIS Control Flow surface has a GUI for expressing task dependancies. It's functional if not not visually outstanding. Your "ETL jobs" could be Execute SQL Task or Execute Process Task objects. You can connect the precedence constraints to show dependancies.

This could either be for real use or just for documentation purposes. If you use it for real you'll find its a great way to control ETL dependancies and parallelism.
