jsPlumb provides a way to “plumb” elements of a UI together.
This page contains examples of the various types of connections you can make with jsPlumb. There are several other demonstrations that offer
a more focused look at some specific part of jsPlumb’s functionality – pick one from the drop down on the left or cycle through Next/Previous.
jsPlumb requires one of jQuery, MooTools or YUI3. See the documentation for a more detailed discussion of requirements.
