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.
You may have tried PowerDesigner, it runs under Eclipse through a plugin and it also supports Visual Studio. The only downside is that it only works on Windows.
Another application for modeling is System Architect from IBM (Popkin). It has been used by some major corporations and is still maintained.

NDepend is certainly the .NET tool you are looking for. It comes with a dependency graph coupled with a dependency matrix. You can try NDepend straight on your code by downloading the free Trial Edition.

With VS2005 & VS2008 you have the option of designing your own modelling language (DSL) here you can choose how your model is rendered, it would be a big investment if its just to make the diagrams look a little better, but it does provide you with option to customise how the code is generated from your model.
Visual Studio 2010 Ultimate supports UML class, sequence, component, use case, and activity diagrams. It also supports creating sequence, dependency graphs, and layer diagrams from code. Other tools include Architecture Explorer, which lets you browse and explore your solution.
