I am relatively new to JavaScript and trying to find a way to get a good overall understanding of JavaScript projects, frameworks, etc.. For example when I look at a JavaScript based source on Github I would like a **one page snapshot of the dependencies between the html, css and the various .js files** requiring further js files( modules) , instead of looking at the source code tree and opening up the individual files. What I am looking for is either an object diagramming tool or something like a "file diagram".

**Is there a tool out in the wild already doing this?** (and ,yes I have already tried Google-ing it) 

(I used to use a [tool](http://www.dependencywalker.com/) in the Windows world for tracking DLLs which is a similar concept.)
