<h2>Graph2d | Dynamic Styling Example</h2> |
|
|
|
|
|
|
|
<div style="width:800px; 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. |
