<h2>Graph2d | Dynamic Styling Example</h2>
<div style="width:700px; font-size:14px; text-align: justify;">
This example shows how to programmatically change the styling of a group. While this can also
be done in CSS, this must be statically defined, and the programmatic interface allows the
user to define the look of the graph at runtime.
