Hi, You have to write your algorithm to make the symbols on the diagram. You define your objects in javascript with properties and methods. The actual drawing can be done by putting SVG element on your canvas with appendChild. The SVG objects have links to the javascript objects.
See how we did it in open-modeling look in /diagram/flowchart/ here is a complex algorithm to determine positions of symbols on a flowchart. Download it at http://sourceforge.net/projects/open-modeling (feedback welcome). In the war file you find the code. Src directories contains the code readable.
