how to install graphviz in my solaris?

someone can help me please? I am trying to install nagvis, but looks like that i need to install this program first. Where do i find steps to install this on my solaris, please?

We don't have a solaris

We don't have a solaris machine available for builds, so you should go to http://www.graphviz.org/Download_solaris.php and follow the link there to download the parts you want.

Alternatively, you can build from source. There are a fair amount of prerequisites, but almost all will be available if you first install gtk+ (http://www.gtk.org/).
