I recently made the acquaintance of Max Gadney - he's responsible for news graphics at the BBC (or at least I think he may have moved on from that role as, googling him, I find his very information-rich job title is Channel Editor, BBC Two & BBC Four, Vision Multi-Platform team). As a sideline he creates terrific information graphics for World War II magazine, like this one.
Have a look at his website.
Max also told me about the Society for News Design.
