Hi everyone. I've just had a discussion with my colleages (I work at the Uni. of Cambridge), and they'd love to have metrics of how content (and other entites) have changed over time; how content, comments, users, etc. have changed over the past days, weeks months, etc.

The idea is for the "editors" of a popular website - who have created a lot of content over a long period of time - to get an idea of how their content has changed over time, along with other helpful things like comments, user signups, etc.

I know there are a lot of typical analytics modules, but are there any good modules that calculates these sorts of things? And do they have nice charts like the attached pic?

*The attached pic is a mockup I just made to discuss this with my team, and to clarify what I'm wanting.

If no module exists like this, would it be helpful if I built it and put it on D.o?
