Viewing Visio Shapes within a windows forms application

Hi,

Task: i would like to view a visio document in my windows forms application on any control, i dont like to open the visio application itself.
Environment: i am using c#, .net 4, visual studio 2010. The visio document will be created in visio 2010. The clients running the application won't have visio installed.

I have searched and read some guides but i dont really get started with it at all.
Is it possible or do the clients need visio?
What library and control can i use for this?

I would be happy about some best practices hints. :)

Thanks!

/edit:

i got this working using this: http://msdn.microsoft.com/en-us/library/office/ff768041%28v=office.14%29.aspx

is it possible to modify or add any shapes within my code after loading?
is it possible to add parameters on loading the vsd file?
