We've created maps of political campaign contributions from companies in the oil & gas and coal industries to congressional representatives. These are relationship map of the contribution network. That means that unlike a physical map, where points are positioned at a geographic location, the icons for the companies and representatives are placed so that they are as close as possible to whomever they contribute to or receive contributions from.
Think of it like a social networking site in which companies and politicians have become 'friends' by giving money.
This site is a project of Oil Change International, developed by Greg Michalec and Skye Bender-deMoll and designed by Diligent Creative. Earlier versions of the site were named 'Follow the Oil Money' and 'Follow the Coal Money'.
