The first thing you should do when you install Roassal is to run the Eassel World Menu>>Tools>Roassal Easel And then select the examples, there are lots of examples and all of them includes the code needed to create the visualization. Also there are a really cool examples in the facebook page of Object Profile, but I can't give you the link since in my network is blocked =(. For more documentation you can see the Roassal and the Mondrian chapters at the Deep into Pharo Book http://www.pharo-project.org/documentation/tutorials-books.
