Having fun recreating the gooey blob effect from this World POTUS project by Accurat and Google: http://www.worldpotus.com
Code initially forked from eesur's block (d3js | circles update with force layout) and then added Nadieh's gooey + color blending effect (Gooey effect - Rotating circles - Blending colors)
