Question: Is there any tool that draws a graphic visualization of a process' memory?

I'd like a graph showing the percentage of pages in physical memory and in the page file.

Answer: 
[Process Explorer](http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx) has several visualization options for both individual processes and the system as a whole.
I use [VMMAP](http://technet.microsoft.com/en-us/sysinternals/dd535533.aspx "VMMap (Systernals)") for this very purpose. 

It's a recent tool made by the Sysinternals team that brought us [ProcessExplorer](http://technet.microsoft.com/en-us/sysinternals/bb896653.aspx) that was suggested in a precedent post.
