CSS examples?

["Richard O. Legendi" <richard.legendi AT gmail.com>]

Hi All,

I would like to create some cool visualization for my displayed graphs, 
something like this you have here:

        http://graphstream-project.org/media/data/stars.png

However, it is a bit unclear for me how to use gradient color 
definitions. Are there any tutorials/code samples about the topic? Or, 
is it possible to find the CSS used for the screenshot above somewhere 
in the project sources?

Thank you in advance,
Richard
