SSIS Diagramming

Hi,

I just want to ask, is there a tool that can create a diagram supporting the SSIS package I have created? I would like to know if there is any available tool that can do this task so that I can support my SSIS package documentation.

For example, I have created a Data Flow task that transfer data from a source database to SQL server 2005 destination. I would like to create a diagram that summarizes the task it perform from source to destination automatically. My purpose is that whenever DB users check my SSIS package, they will have a concise idea of how my SSIS package works through my diagram.

If ever you have any ideas about this, please help.

Thanks in advance.
