How to embed Freenode IRC's into my website

I have embedded our organization's Chatroom using Kiwi IRC widget into my website's webpage using Kiwi IRC embedding code for my users to talk/chat with other users and that works fine.
Is there anyway so that I can embed all of Freenode IRC channels onto my single webpage like Embedding a Kiwi IRC widget into your website, so that if any user want to explore the knowledge through more than one IRC's then he/she can easily join/access other IRC channels. Finally, I want to include Freenode channels too.

Regards,
