Hi,
I'm new to Office '08, and I am struggling with making a flow chart look right. I want it to be a circular flow chart in essence, but I want to be able to show items that branch out, and remove the flow from the cycle. This seems like something that should be done easily enough, but I haven't been able to figure it out. Any help is greatly appreciated!
Best,
P

To be clear, I'd like advice on making more complex flow charts in general. For example: is there a way to make two interlocking circular flow charts using SmartArt Graphics?

Thank you,
P
