I normally do a survey for Dedicated server pricing in the UK every month as part of my job, this ends up in a massive spread sheet that to be fair I am normally the only one that ever uses.
However I have change the way that I display the information, being that humans take in information more easily in a graphical form. Any hoo, this is the result, I am also rather please to have found a cool little application from zoom.it that allows you to zoom in and out and do all the cool swooshie things.
This I might add is a cut down version of the map only showing the major companies.
