In Visual Studio 2005 and prior you could export your code to Visio and view the relationships between the objects and what methods, properties and fields it had. This was great as it allowed you to tweak the appearance to improve the look.
In VS 2008 that option is gone, replaced (supposedly) with the class diagram system. It is functional but not pretty.
What I am looking for is some software that allows me to visualise in a prettier way or at least provide me with enough options to filter, arrange and so on so that I could touch it up in something else.
