Jason Davies	7f8db7fd14	Remove force.gravityCenter. ... Simpler to perform gravity calculations in a custom tick handler.	2011-07-09 00:24:17 +01:00
Jason Davies	ca8870778a	Add per-node gravity: force.gravityCenter. ... This allows the Dorling/Demers cartograms to be slightly closer to the real geography. Also, fix the Dorling collision detection as self-collisions were previously being detected. Thanks, Mike! Lastly, I've removed the variable per-link distance as this is no longer needed.	2011-07-08 23:23:50 +01:00

Jason Davies	bb5d7873a7	Use collision detection for Dorling cartogram.	2011-07-08 22:11:49 +01:00
Jason Davies	679d816dfd	Initial version of Dorling cartogram example. ... This version uses variable-length links, but I think collision detection performed after initial positioning at state centroids would look better.	2011-07-08 21:55:31 +01:00
