Now JsDiagram can use jQuery for browser abstraction instead of Microsoft Ajax. If anyone is interested in trying it, please download this archive containing a pre-release mindfusion.diagramming.js build and a sample page:
https://mindfusion.eu/_beta/jsdiag_jquery.zip

To enable jQuery support, set MindFusionImpl="JQuery" before loading the diagram script:

<script type="text/javascript">
    MindFusionImpl = "JQuery";
</script>
<script src="jquery-1.7.1.js" type="text/javascript"></script>
<script src="MindFusion.Diagramming.js" type="text/javascript"></script> 

Instead of MSAjax $create function, use the static Diagram.create(element) method to create a Diagram instance for given Canvas element:

diagram = MindFusion.Diagramming.Diagram.create($("#diagram")[0]); 

Any comments, questions and general feedback are welcome.

There aren't, the diagram uses it mostly for event handling and the event API should be the same since JQuery 1.11.
