jsPlumb provides a means for a developer to visually connect elements on their web pages. It uses SVG or Canvas in modern browsers, and VML on IE 8 and jQuery.jsPlumb adds an element to the DOM for each Endpoint, Connector and Overlay. So for a connection having visible Endpoints at each end and a label in the middle, jsPlumb adds four elements to the DOM. The actual elements it adds depend on the renderer in use (Canvas/SVG/VML).
