Perfect timing, just learning how to make a map in d3 for Bower stats [1]. Thought after experimenting with choropleth maps [2], bubbles on maps and dorling maps [3] [4], dorling maps appear to be the best way to show very dense info on relationships with vague references to geography.

could you explain your opinion? I'd say the choice between choropleth and dorling maps depends on what sort of data you want to present, or am I missing something? What I mean is, if the bubble size represents a different information from the color depth (i.e. figure 10, page 12 f the dorling paper shows population as a bubble, AFAICT) than it makes sense, but if it's just another encoding of already represented information it seems weird. I.e. in the "dorling world" map I have lost plenty of informations (I have no idea what northern and eastern europe countries are what anymore, while I can tell them at a glance on a normal map) but I have not gained anything.
