Another method of exploring large graphs is to use the panner window (see Figure 3). The main window shows a magnified view of part of the graph whereas the panner window shows a scaled-down view of the whole graph. The magnified part of the graph is marked by a rectangle (surrounded by a dashed line) in the panner window. Dragging this rectangle in the panner window enables the virtual window to be moved over the graph. The virtual window can be positioned anywhere by clicking that position in the panner window. To open the panner window, select Panner from the Scroll menu in the menu line (see Figure 2).
