Looking to visualize debugging: variables and instances created by classes and functions graphically drawn

First of all, I do not believe this belongs on Superuser. This belongs here bec开发者_运维知识库ause it is strictly programming related.

What I am looking for is a program that will visualize(draw it on the screen or something) how programs create variables, make pointers from the stack to the heap, variable names and contents, and so on.

Kinda like a diagram/flowchart thing, but automatically drawn for you.

Does such a thing exist?

EDIT: i just came across this topic: Visualizing the code involved in an action?, that's not what I'm looking for, I'm talking about some really graphic and dynamic.

EDIT:

I found 1 thing, but it's not really great and kinda old.

If you are working on one of the UNIX platforms, you might want to look at DDD.
