I posed this question on Stack Overflow just yesterday:

How can I visualize the javascript used by a given url?

Someone at work just showed me our site on cssstats.com and I really like the way it illustrates the bloat and redundancy in our website's stylesheets. An example:

http://cssstats.com/stats?url=http%3A%2F%2Fstackoverflow.com...

I was wondering if there was something comparable for javascript. I did some googling but couldn't find anything myself.

I'm looking to convince management (most of which is non-technical) to invest some time in refactoring and simplifying our stylesheets and javascript and I think something like this (not necessarily a "a book, tool, software library, tutorial or other off-site resource" but, yeah, something like that) would really help make my case.

This particular visualization isn't quite what I'm looking for. But it is interesting. I'm tempted to run our code base through it. I'm afraid it will come out a sprawling slum. But then I guess that would be my point.

Epilogue: Stack Overflow question was immediately killed as off-topic. Which flashed me back to this thread: https://news.ycombinator.com/item?id=11890140
