Interaction. Drawings inside the plug-in can be interacted with by the user. Such interaction is actually built into the drawings itself during construction, but is supported by the plug-in.
Animation. All graphical object have attributes called resources that can be modified - both statically within the editor, and dynamically within the plug-in. Resource values and update requests can be fed into the plug-in from an associated data plug-in or from the web server.
Navigation. Graphical objects in the drawing can be named. This is what allows their attributes to be modified by a data stream. If an objects name begins with http:, then the object is cosidered to be a link to the given URL.
