Visualization of Publication Edits

Hi all,

I'm interested in finding a way to visualize the changes to a publication over time. I was wondering if anyone has discovered a way to determine what topics have been changed, how many times they have been edited, what has been added or deleted, etc. Is this something that already exists within a predefined tool? Or that anyone has managed to figure out through a non-SDL tool? I am hoping to create some kind of visualization from that data.

Thanks!
