JavaScript Wiring Library: WireIt (Like Yahoo Pipes)

Most of us are familiar with the beautiful interface of Yahoo Pipes, how objects are wired to each other.

There is an open source JavaScript library, which enables you to create a such visuality, named WireIt.

The library is very suitable for creating dataflow applications (like a family tree) or visual programming languages.

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

It uses the YUI library for DOM and events manipulation, and excanvas for IE support of the canvas tag.
