Chicago Lobbyists Force-Directed Graph Visualization - Christopher Manning This visualization includes the 50 highest paid lobbyists in Chicago, their clients, and the agencies they lobby. The data was compiled from in 2010. Blue Nodes: Lobbyists Grey Nodes: Clients Green Nodes: Agencies The radius of the Blue(Lobbyist) and Grey(Client) nodes is relative to the amount of money associated with them. The radius of the Green(Agency) nodes is constant and does not represent anything about that agency. Nodes closer to the center have more connections than nodes on the outer edge. Controls Hover a node to highlight the connected nodes and show the names and dollar amounts associated to that node.
