Hi Christophe, Chuks,

There's also an example of basic (clickable) visualization at LCSH.
See the "Visualization" tab at

>> Hi Guys,
>> I need a great favor from you. Am completely new to SKOS, i have been working on it for less than a month now, reading tons of materials, trying to get a grasp of what it is all about. Now i can say that , at least it makes sense. I have a limited time to understand all this , then try to develop a a Visualization software for SKOS that takes a SKOS file and transforms it into a directed graph of concepts and relationships. I need your help and Guidance because, i honestly dont know how to start. I have spent time learning about apps like protègè, ThManager..etc. I have also spent time on the Jena API for java, trying to get a grip. If there's anyone out there who has worked on this visualization software before, please come to my aid.
>> Sincerely,
>> Chuks.
