I require HELP with CDS Question

Hi Folks

I was hoping someone on this forum can help me, my question is as follows.

Q; Where can I go to obtain information regarding CDS (credit default swaps) on an individual countries depth ? Is this type of information only available from say a Bloomberg feed ?

I've noticed that every now and again the brilliant people here at Zero Hedge put up a blue and red coloured chart that shows the CDS being traded on individual companies. Do I have this wrong, are there also charts like this for individual counties showing the CDS on it's depth?????

If anyone can help me to shed some light on this I would be greatly appreciative.

Thanks
