It is important for analysts to realize the connection between two distant nodes in a graph, which is not readily supported by existing space-filling techniques. We developed an experimental prototype, FocusTree, which displays graphs in two view modes: fisheye or tree. In fisheye view, selected nodes and the nodes connecting them remained full-sized while the other nodes were reduced in size. In tree view, all nodes remained the same size, regardless of selection state. We conducted a study to compare the speed of participants using the fisheye view to the tree view when determining the number of links between two nodes. There were two states for the degree of separation in the tasks: simple (four links) and complex (eight links). Results showed a main effect for view type with fisheye view being significantly faster than tree view for determining the connection between two nodes.
