But you wonder if something like this isn’t the future of news browsing. Can you imagine what happens when tagging technology gets truly semantic–when stories can be linked not just with keywords, but ideas?

It is also called spatialization which make a map out of a non-geographic dataset.

Having played with these graphs a little I think it is the right call. IMHO, a better way to represent strength is to create a dichotomous "connections strength" variable and use that to create "transparent/solid" links. Use the histogram of connections to decide where a reasonable cutoff is. For example, "more than 5 connections" is 1 and "less than 5 connections" is 0. Then make the connections that are 0 transparent (or light blue). Keep the connections that have the value of 1 solid (or dark blue).

Isn't that the way all these network-viewing software work ? (I might be very wrong, of course). I suspect distance is somewhat arbitrary and is about readability.
