It's a pretty picture, but a lot of the 'attacks' they list are pretty basic script kiddy tools and/or bot net generated. Given the number of active attacks they list at any given time compared to the number of hosts in any of those countries the numbers are a lot smaller than I'd have guessed were going on at any given time. .. especially for DDOS attacks. Getting hit by a DDOS from a fairly small number of IPs for a tiny interval shouldn't be too scary for any sys admin.
It would be impressive to execs if we put it up on one of our control center screens though....
