Does anybody know what type of chart that is? (some sort of bubble chart but with links between bubbles)

I'd just call it a directed graph (digraph) where the nodes have values (fields, attributes) which are expressed as visual attributes (size, color, label). I'm using "graph" in the mathematical sense and not as a synonym for "chart".
Such graphs can be drawn with graphviz, and other software. (Though I'm not sure how to achieve the gaudy 3D effect.)

3$\begingroup$ Since the connections have a direction (arrows) it could be called a directed graph. $\endgroup$ Sep 20, 2013 at 21:10

$\begingroup$ @GregSnow: Excellent point. I'll edit to add that. $\endgroup$– WayneSep 20, 2013 at 21:34

2$\begingroup$ What distinction are you making between "directed graph" and "directed network graph"? $\endgroup$– whuber ♦Sep 20, 2013 at 21:36

2$\begingroup$ The nodes have values (which determine the size and apparently the colours) $\endgroup$– HenrySep 20, 2013 at 22:15

1$\begingroup$ @whuber: Good point. I've deleted the word "network", but added a sentence to explain that the usage of "graph" (which in popular usage can be synonymous with "chart"). $\endgroup$– WayneSep 20, 2013 at 23:01
