Mouse over congress members and PACs to see a summary. Zoom into the outer category by clicking the outer bars. Show the connections between the two groups by clicking on the inner bars. Connections grow in height, pulling blocks out on the opposite side. Double-click the inner bars to show or hide all blocks in the group.
