After you set the data source, you can customize the
way it is displayed. You can use Cascading Style Sheets (CSS) to style
your data. CSS can be applied with a styleSheets attribute:
<jvdf:diagrammerView id="diagrammer" [...] styleSheets="data/diagrammer.css" />
The CSS file must be present in the data directory of
the Web application. The style sheet file specification can also be
a value binding, that is, a value provided by a bean.
