WireIt: Javascript wiring library

one thing i was always trying to figure out, is how to make lines in HTML/JS, after recently finding out about the Yahoo Pipes interface i came across this lightweight library that does the same thing, show objects are wired to each other.
There is an open source JavaScript library, which enables you to create this "wired interface", named WireIt.


WireIt is very well-documented & has some attractive examples.
