I was trying to code it in the encodeBegin, but nothing displayed. I'll try
to code in the encodeEnd() method, following the schedule like you said.

I think that the best option to see how to implement a component is
directly check out the sources for the tomahawk/sandbox components.
Every component has the component, tag, and renderer implementation.
You can check the faces-config.xml file to see how this components are
registered and also the tld.
About your specific questions: you don't need any binding if your
component has everything in it (save/restore state, etc). Just pass
the model to the value attribute (I guess it should be something like
value="#{bean.graphicModel" (without the getter)). Take a look at the
schedule component, as it accepts a custom model object.
The encodeBegin is optional as long as your component does not render
any children. When a component has children, the method encodeBegin is
called before and the encodeEnd afterwars. In your case, I guess you
only need the encodeEnd in your renderer object (recommended).
HTH,
